2/1- Classwork

Solve for x:
5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

Solve for f: 1f - 4 = 6f + 26

• f = -5
• f = 5
• f = 6
• f = -6

10x + 9 = 4x - 9

• x = 0

• x = 3

• x = -3

• x = -18

7w + 5 = 3w - 15

• w = 5

• w = -2

• w = 2

• w = -5

-5k + 10 = -2k - 14

• k = 8

• k = -8

• k = 2

• k = -2

Solve the equation
12x - 15 = 3(2x+3)

• x = 4
• x = -4
• x = 2
• x = -2

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

7x - 4 = 3 + 8x

• x = 7
• x = -7
• x = 2/7
• x = 11

Simplify the expression:
8(5 + w)

• 40 + w
• 40 + 8w

• 85 + 8w
• 13 + 8w

n - 1 = -11

• n = 5

• n = 10

• n = -10

• n = -11
