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.

-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.

Solve.  -7x - 11 = 3

• 2

• 14

• -8

• -2
