Solve: 7x = 3x + 24

• 10

• 4

• 6

• 14

Solve: 10x + 9 = 4x - 9

• x=3

• x=0

• x=-3

• x=18

Solve for a:

-3a + 8 = 14

• a = -2

• a = -7.5

• a = 2

• a = 6

Solve for x:

2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5

• x = 15

Solve for b:
 3(b - 4) = -3

• b = 3
• b = -3
• b = 5
• b = -5

12x = 144

• x = 12
• x = 4
• x = 2
• x = 132

What would be the best first step to solving the equation?

-18=x+12

• add 18 to both sides

• add 12 to both sides

• subtract 18 from both sides

• subtract 12 from both sides

Where do these two lines meet?

• (2, -9)
• (-9, 2)
• No solultion
• (2, 9)

The solution to the system is

• (-2, -8)
• (-8, -2)
• (2, -8)
• No solution

Which is the graph of y= -x + 2?

• A
• B
• C
• D
