Answer:
D
Step-by-step explanation:
Given the 2 equations
2x - 3y = 14 → (1)
5x + 3y = 21 → (2)
Adding the 2 equations term by term will eliminate the y - term
(5x + 2x) + (- 3y + 3y) = (14 + 21)
7x = 35 ( divide both sides by 7 )
x = 5 → D

Answer:
w=63, x = 86, y=38 and z = 25 degrees
Step-by-step explanation:
w + 117 = 180
so w = 180 - 117 = 63 degrees.
x = 180 - 63 - 31 = 180 - 94
= 86 degrees
y = 180 - 86 - 56 = 180 - 142
= 38 degrees
z = 180 - 117 - 38 = 180 - 155
= 25 degrees
