Angle ABC and angle BD are complementary. The measure of angle ABC equals (3x + 4) degrees, and

the measure of angle CBD equals (5x +6). Find the measures of both angles.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
