Answer:
No
Step-by-step explanation:
x + (-8x - 3) = 7
x -8x - 3 = 7
-7x = 10
x = -10/7
y = -8(-10/7) - 3
y = 80/7 - 3
y = 59/7
Answer:
42°
Step-by-step explanation:
angle 3 + angle 4 = 180° because together they make a straight line. So your equation should be 23x + 7x = 180. Add the like terms and you get 30x=180. Divide by 30 on both sides to get x. now you know that x=6. angle 4 = 7x. so you would multiply 7*6 to get 42. Thus angle 4= 42°
