-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

-5 - 6a = -59

• a= 11
• a= -6
• a= 9
• a= 2

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

What step would be used to solve for the "variable term" first?

• add 16 to both sides
• divide both sides by 3
• multiply both sides by 3
• subtract 5 from both sides

Where/what is the mistake?

• Line 2 - You should add 12 to both sides.
• Line 4 - You should multiply both sides by the reciprocal.
• Line 4 - You should multiply both sides by the original fraction. 
• Line 5 - There was a calculation error.

• u = 10

• u = 76

• u = 40

• u = 19

7 = 6w + 34 + 3w

• w = 3

• w = -3

• w = -9

• w = 9

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

• None of these
