Chapter 6 7th grade

Solve for a:

-3a + 8 = 14

• a = -2

• a = -7.5

• a = 2

• a = 6

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

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

Solve the equation
4x - 5x + 9 =5x - 9

• x = -3
• x = 9
• x = 3
• x = -9

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

3x + 2(4x - 4) = 3

• 4
• 3
• 2
• 1
