1.2-1.4 Test Review

What is the first step to solve? l 4x−3 l = 17

• separate into two equations, one with 17 and one with -17

• add 3 to both sides

• divide both sides by 4

• There is no solution so no need to keep going

What is the first step to solving?

−2|−2r − 4| = -12

• Create two equations, one equal to 12 and one equal to -12

• divide both sides by -2

• add two to both sides

• distribute -2

What is the first step to solve?

|8 - 4x| = -16

• create two equations, one equal to 16 and one equal to -16

• subtract 8 on both sides

• divide by -4 on both sides

• there is no solution so no need to solve further

What is the first step to solve for x

2lx − 4l + 8 = 18

• divide both sides by 2

• distribute 2

• subtract 8 on both sides

• create two equations, one equal to 18 and one equal to -18

What is the first step in solving for x

7 - |3x - 4| = 12

• add 7 to both sides

• subtract 7 from both sides

• divide both sides by 7

• create two equations, one equal to 12 and one equal to -12

Which two equations would we create to solve the following absolute value equation. CHECK ALL THAT APPLY

|x + 5| = -4 + 8x

• x + 5 = 4 + 8x

• x + 5 = -4 + 8x

• x + 5 = -4 - 8x

• x + 5 = 4 - 8x

What is the first step in solving for x

-3(2x - 9) + 5x = 13

• divide both sides by -3

• subtract 5x

• distribute -3

• combine like terms

When solving an equation, we get to the step:

-7x + 6 = -7x - 9

what can we conclude about our answer

• x = -15

• x = -3

• there is no solution

• all real numbers will balance this equation

What is the first step in solving the equation for x

15x - 19 + 4x - 9x + 7 = -45

• distribute

• there is no solution so no need to solve further

• create two equations, one equal to 45 and one equal to -45

• combine like terms

Solve for x

|3x| + 2 = 8
