Answer: x=68/11 and y=-72/11


Steps:

2(x+4y=-20)

2x+8y=-40

2x - 3y = 32
- 2x + 8y = -40

-11y=72

y=-72/11


x + 4(-72/11) = -20

x - 288/11 = -20

x=68/11

topjm [15]

Answer:

100°

Step-by-step explanation:

Since the angles om a straight line add up to 180°

10x°+8x°=180°

18x°=180°

x=10

The larger angle = 10x°

= 10(10)°

= 100°
