How to Solve Equations of the Form x ± b = ± c

A one step equation is a mathematical statement of the Form x ± b = ± c, where you solve for a variable (usually x) by performing a single operation - either addition, subtraction, multiplication, or division. For example: x + 3 = 12 and x - 5 = 10 are one-step equations.

Equations of the Form x - b = ± c

When solving one step equation of the form x - b = ±c, add b to both sides of the equation. 

x - b = c

x - b + b = c + b

x + 0 = c + b

x = c + b

Example: x - 2  =  8

x - 2 = 8
x - 2 + 2 = 8 + 2
x + 0 = 10
x = 10

Example: x - 4 = -6 

x - 4  =  -6
x - 4 = -6
x - 4 + 4 = -6 + 4
x + 0 = -2
x = -2

Equations of the Form x + b = ± c

When solving one step equation of the form x + b = ± c, subtract b from both sides of the equation.

x + b = c

x + b - b = c - b

x + 0 = c - b

x = c - b

Example: x + 3  =  8

x + 3 = 8

x + 3 - 3 = 8 - 3

x + 0 = 5

x = 5

Example: x + 5  =  -10

x + 5 = -10

x + 5 - 5 = -10 - 5

x + 0 = -15

x = -15
