-3x + 2y = 56
-5x - 2y= 24

(- 10, 13 )

Step-by-step explanation:

Given the 2 equations

- 3x + 2y = 56 → (1)

- 5x - 2y = 24 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

- 8x = 80 ( divide both sides by - 8 )

x = - 10

Substitute x = - 10 into either of the 2 equations and solve for y

Substituting into (1)

- 3(- 10) + 2y = 56

30 + 2y = 56 ( subtract 30 from both sides )

2y = 26 ( divide both sides by 2 )

y = 13

Solution is (- 10, 13 )

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°
