Answer:
x = 9
Explanation:
7x + 3 = 10x -24
3 = 10x -7x - 24
24 + 3 = 10x - 7x
27 = 3x
27/3 = 3x/3
9= x
x=9
The angles are vertical angles, which means they are equal
7x+3 = 10x-24
Subtract 7x from each side
7x+3 -7x = 10x-7x-24
3 = 3x-24
Add 24 to each side
3+24 = 3x-24+24
Divide each side by 3
9 = x
