Solve a Two Step Equation

Solve for n.

2n + 10 = -2

• n = -14

• n = -10

• n = -24

• n = -6

• n = -12

Solve for x.

4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12

Solve for z.

6z + 3 - 4z = 9

• z = 3

• z = 60

• z = 30

• z = 1

Solve for y.

-15 = -4y + 5

• y = -5

• y = 5

• y = -24

• y = -16

• y = 80

Solve for c.

3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18

• a= -2

• a= -6

• a= 3

• a= 15

What are the steps to solve for b in the equation below?

• Add 6 to both sides then divide both sides by 5

• Add 6 to both sides then 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

• w = 2

• w = 4

• w = 6

• w = 8

Solve for x.
9 + 3x  =  10

• 4

Did Sarah make an error? If so, which is the best description of her error?

• She didn't distribute correctly. The second step should read 3x - 12 = 24

• She didn't distribute correctly. The second step should read -3x - 12 = 24

• She didn't distribute correctly. The second step should read -3x + 12 = 24

• She didn't make an error.
