Equations and Inequalities (keypoints)

Label each term or part with the correct name.

a

c

b

constant

variable

constant

Reorder the following steps for solving a two-step equation like:

2x-5=13

• then use inverse operation of the variable term make sure you do it to both sides.

• move the constant that's on the same side with variable using inverse operations

• Label the terms

• use the same inverse operation on the other side

• check your answer

To solve 2x-5=13, first I will ​ (a)   my terms as either ​ (b)   or ​ (c)   . Then I would ​ (d)   5 to both sides. This would make a ​ (e)   pair on the left side and 18 on the right side. Then I would divide both sides by 2. This would leave 'x' on one side and 'x' would equal nine
