In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation?
Subtract 7 from both sides.
Subtract 12 from both sides
Multiply both sides by 7
Add 12 to both sides
x + 7 = 12
x - 4 = -3
x - 3 = -12
S + 4 = 24
S = 28
S = 6
S = 18
S = 20
x - 12 = 2
