Solve the following system by elimination:
4x+3y=2
5x + 4y = 3

5x+4y=3

- 4x+3y=2

x+y=1

x = -1, y = 2   ( -1, 2 )

Step-by-step explanation:

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°
