HW: week ending 11/4

Solve: 5x + 15 = 10x - 40

• x = 10

• x = -10

• x = 11

• x = -11

Solve: -2x + 18 = 2x + 40

• x = -5.5

• x = 6.5

• x = -4.5

• x = 5.5

Solve: 4x - 3 = 6x - 19

• x = -8

• x = 11

• x = -11

• x = 8

Solve: 12x + 1 = 6x - 47

• x = 6

• x = -7

• x = -8

• x = 9

Solve: 3x + 16 = 7x + 64

• x = 10

• x = -10

• x = -11

• x = -12

Solve: -3x + 20 = 2x - 40

• x = 15

• x = 12

• x = -15

• x = -12

Solve:
7x = 3x + 24

• 6
• 10
• 14
• 4

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

• add 1 to both sides

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

• add 2 to both sides

12 - 5k = k + 6

• k = 1

• k -1

• k= 1/2

• k = -1/2
