Solve m - n = 5 for m.

• m = 5 + n

• m = -5 - n

• m = -5 + n

• m = 5 - n

S = 3F - 24  Solve for F

• F = (S + 24)/3

• F = S/3 + 24

• F = 3S + 24

• F = 3(S + 24)

Solve for t.
D= rt

• D/r = t

• Dr = t

• D/t = r

• Dt = r

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

3x + 2 = 5
