Two Step Equations

Two Step Equations

by Darius Wilson

​Coefficient- the number that is attached to the letter( Variable)

​Here are some examples of coefficient.

• ​5x +10 =25

• ​-2z - 12= 32

• ​7w + 14= 21

• ​15 - 30x = 45

• ​.5= .2t + .8

​Constant- the number that is on the same side as the coefficient, but does NOT have the letter attached.

• ​​5x +10 =25

• ​-2z - 12= 32

• ​7w + 14= 21

• ​15 - 30x = 45

• ​.5= .2t + .8

​Steps to Solve

• ​S0... Split your equation in half.

• ​S1... Eliminate the constant by doing the opposite operation on both sides of the equal sign to create a zero pair.

• ​S2... Divide the coefficient on both sides to get your variable by it's self

• ​Your goal is to get your variable by it's self.

​Eliminating Fractions

• ​Find a common denominator.

Distribute the common denominator to the ENTIRE problem

​

• ​S0... Split your equation in half.

• ​S1... Eliminate the constant by doing the opposite operation on both sides of the equal sign to create a zero pair.

• ​S2... Divide the coefficient on both sides to get your variable by it's self

• ​Your goal is to get your variable by it's self.
