Solving equations using subtractionWhen solving equations using subtraction, they will have this form: x + b = c Recall that ax + b = c is a linear equation. Therefore, the equation x + b = c is a linear equation with a = 1. To see this, notice that 1.x = x Thus, we can rewrite x + b = c as 1.x + b = c You can solve x + b = c in one step. When solving one step equation of the form x + b = c, subtract b from both sides of the equation. Let us illustrate with examples: Example #1: Solve x + 3 = 8 for x Alternatively, you do not have to put the 3 beneath the 3. You can also put it next to it. x + 3 = 8 x + 3 − 3 = 8 − 3 x + 0 = 5 x = 5 Example #2: Solve x + 5 = 10 for x Example #3: Solve x + 5 =  10 for x
