Solving equations 8 Pre-test Warm-up We can think of an algebraic equation as being like a set of scales. The two sides of the equation are equal, so the scales are balanced. If we add something to one side of the scales without adding something to the other side, the scales will no longer...

Solving And Checking Equations In math there are many different types of equations to solve and check. Some of them are easy and some are hard but all of them have some steps that need to be followed. To solve the problem 2(7x-4)-4(2x-6)=3x+31 you must follow many steps. The first thing you will...
Colleen Cooper Solving Quadratic Equations MAT 126 Survey of Mathematical Methods Instructor: Kussiy Alyass October 1,, 2012 Solving Quadratic Equations Using correct methods to solve quadratic equations can make math an interesting task. In the paper below I will square the coefficient...
To solve a system of equations by addition or subtraction (or elimination), you must eliminate one of the variables so that you could solve for one of the variables. First, in this equation, you must look for a way to eliminate a variable (line the equations up vertically and look to see if there are...
1. Solve S = 4v2 for v.(1 point) Get rid of 4 by dividing both sides by 4 s/4 = v^2 +/- square root of (s)/2=v 2. Solve M = 2x + 3y for y. (1 point) 3y= m - 2x y= (m - 2x)/3 y = (m - 2x)/3 3. Solve t = p+r/ 6 for r. (1 point) t = p + 3r / 6 t - p = 3r / 6 Divide both sides by 6 ...
Solving Exponential and Logarithmic Equations Exponential Equations (variable in exponent position) 1. Isolate the exponential portion ( base exp onent ): Move all non-exponential factors or terms to the other side of the equation. 2. Take ln or log of each side of the equation. • Make sure to use...
that hold true for the equation, solving quadratic equations requires much more than simply isolating the variable, as is required in solving linear equations. This piece will outline the different types of quadratic equations, strategies for solving each type, as well as other methods of solutions such...
There are two main ways to solve equations, algebraically or by using matrices. There are also different subcategories of each way to solve the equations. Using matrices or solving algebraically has some differences and similarities. There are a few ways to solve equations algebraically. One line of...
What Factors Should I Consider When Choosing a Career? Some people spend their entire lives asking themselves what they want to be when they grow up. Other people know from childhood and by following an interior compass, they end up in a career that never feels like going to work. If you're somewhere...

In mathematics, an equation is a formula of the form A = B, where A and B are expressions that may contain one or several variables called unknowns, and "=" denotes the equality binary relation. Although written in the form of proposition, an equation is not a statement that is either true or false,...
equation In mathematics, an equation is an equality containing one or more variables. Solving the equation consists of determining which values of the variables make the equality true. In this situation, variables are also known as unknowns and the values which satisfy the equality are known as solutions...
