Solving equations using subtraction
When solving equations using subtraction, they will have the following 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
Example #2: Solve x + 5 = 10 for x
Example #3: Solve x + 5 = - 10 for x
