Post Assessment Solving Linear Equation Part 2

Solve for x: |2x + 3| = 7

• x = 3, -4

• x = 1, -8

• x = 0, -7

• x = 2, -5

Find the solution to |5 - 3x| = 11

• x = 0, x = 7

• x = -2, x = 6

• x = 3, x = 8

• x = -5, x = 2

Solve:

• z = 4/9 & z = 20/7

• z = -4/9 & z = 20/7

• z = 9/4 & z = 20/7

• z = 4/9 & z = -7/20

Convert the formula A = 1/2bh to solve for h

• h = 1/2Ab

• h = 1/2bA

• h = 2A/b

• h = 2b/A

Given the formula C = 2πr, rewrite it to solve for r

• r = C * 2π

• r = C / 2π

• r = C + 2π

• r = C - 2π

• -3

• 0

• 17

• 3, -17

Solve the absolute value equation.
|4x−2|−6=20

• 1. x = 4, x = -4

• 1. x = 2, x = -2

• 1. x = 6, x = -7

• 1. x = -6, x = 7
