Answer:
a = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 - 10 = 2a - 10
Simplify:
7a = 2a - 10
Subtract 2a from both sides:
7a - 2a = 2a - 10 - 2a
Simplify:
5a = -10
Divide both sides by 5 and simplify:
a = -2

ANSWER : both angles are 60 degrees and x is equal to 8.
10x - 20 = 7x + 4
Move the terms
3x = 24
x= 8
Sub back in to find the value:
80 - 20 = 60
56 + 4 = 60
