Match each set of equations with the move that turned the first equation into the second.

a.6x + 9 = 4x-3. 1. multiply both sides by-1/4
2x + 9 = -3. 2. multiply both sides by -4
b.-4(5x-7) = -18. 3. multiply both sides by 1/4
5x-7 =4.5. 4. add -4x to both sides
c.8–10x = 7+5x. 5. add -4 to both sides
4-10x = 3 + 5x
d. -5x/4 = 4
5x = -16
e. 12x + 4 =20x + 24
3x + 1 = 5x + 6

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
