How to solve Two-Step Equations?
Two-step equations involve two math operations - one operation is addition or subtraction. The second operation is multiplication or division.
To solve a two-step equation, follow the order of operations backwards - add or subtract, then multiply or divide to solve for x.
Example 1: Solve for x.2x-1=3 2x-1+1=3+1 First we add 1 to both sides of the equation.2x=4 2x/2=4/2 Now we divide both sides of the equation by 2.x=2
Example 2: Solve for x.x/2 +1=7 x/2+1-1=7-1 First we subtract 1 from both sides of the equation.x/2 =6 2.x/2=2.6 Now we multiply both sides of the equation by 2.x=12
