2-Step Equations

What is the first step, when solving for x in this problem?

x/7 + 5 = 20

• Multiply by 7 on both sides

• Divide by 7 on both sides

• Subtract 5 from both sides

• Add 5 from both sides

What is the inverse operation (opposite) of division?

• Addition

• Subtraction

• Division

• Multiplication

Solve X:

12x - 20 = 16

• X = 3

• X = 480

• X = -0.33

• X = 1/2

Solve for v:

2v + 7 = 3

• v = 5

• v = -2

• v = -8

• v = 20

solve for b:

4b + 3 = -9

• b = -24

• b = -48

• b = 1.5

• b = -3

8n + 16.2 = 1.6

• n = 0.333

• n = -1.825

• n = -0.175

• n = 1.348

What is the second step when solving for x in this equation?

2 - b/3 = 8

• b = 3.33

• b = -12

• b = -18

• b = 9

17 = 5k - 2

• K = 3

• K = 75

• K = 95

• K = 3.8

Solve for N:

N/4 - 4 = 12

• N = 4

• N = 2

• N = 16

• N = 64

g/-5 + 2.3 = 18.8

• g = 104

• g = 4.16

• g = -82.5

• g = 3.36
