Unit 2 Review

What is the value of x in

2(4 - x) = -5x - 19

• -9

• -11/3

• 1

• 0

Solve: 6x - 4 + 3x = -13

• x = -1

• x = -2

• x = -3

• x = -4

Match the equivalent equations.

• 3x - 2 = x + 3

• 7x + 1 - 2x = 2x + 5

• 5x = 5

• 5x - 4 + 2x = 0

• 3x = 4

• 2(3x - 2) = 2(x + 3)

• 7x = 4

• 2(x + 1) = 7 - 2x

• 4x - 2 = 3

• 6x - 4 = x + 1

Find the solutions for m: 10m + 15 ≤ -7(-2m - 1)

• m ≥ -2

• m ≥ 2

• m ≤ 2

• m ≤ -2

Select every given solution to 3 - 2x > 1

• 1

• -2

• 1.5

• 0

• -100

What step should be done next to solve for y with -2y = 4x - 16

• Combine 4x and -16

• Add 2 to both sides

• Divide everything by -2

• Add 16 to both sides

Solve for y: 0 = 12 - y + 18x

• y = 12 + 18x

• y = 12 - 18x

• y = -12 - 18x

• y = 30x

Solve for h: 2h - 4x = -6y

• h = 2x - 3y

• y = -1/3h +2/3x

• h = 3y + 2x

• h = -3y - 2x

Select every given solution to 6x + 3y < 24

• (0, 0)

• (5, -2)

• (-1, 4)

• (-3, -5)

• (7, 7)
