The sum of two angles is 180 degrees. Their difference is 70
1 answer:
Step-by-step explanation:
x+y=180
x=180-y------(i)
x-y=70------(ii)
Now,
Putting the value of x in equation (ii)
x-y=70
(180-y)-y=70
180+2y=70
2y=70-180
2y= - 110
y= - 110/2
y= - 55
Again,
x=180-(-55)
x=235
x-y=70
x-(-55)=70
x+55=70
x=70-55
x=15

4a - 14 = 7a - 8
4a - 7a = 14 -8
