Solving for a Variable

Special Cases

Example 10

Solve 11 + 3x - 7 = 6x + 5 - 3x

Step 1. Combine like terms that are on the same side of the equation.

Solve_ex10-1

Step 2. From the resulting equation, subtract 3x from both sides.

Solve_ex10_2

Since 4 = 5 is a false statement, there is no solution.
