<span>2x+14y=-108
</span><span>63x+14y= 14 (multiply the second equation by 7 and subtract)
_____________
-61x=-122
x=-122/-61
x=2
2(2)+14y=-108
4+14y=-108
14y=-112
y=-112/14
y=-8

Answer:
b = 2a + c
Step-by-step explanation:
Given
a =
(b - c)
Multiply both sides by 2 to clear the fraction
2a = b - c ( add c to both sides )
2a + c = b
Each of the angles in a triangle are 60 degrees, so when you add them together, you get 180
60+60+60=180
