Please help this geometry problem

Answer:
Step-by-step explanation:
I'm going to assume that you want the value of x.
[(2x + 4) + 4]/(2x + 4) = [x + 7 +3)] / (x + 7) Combine like terms on the numerator.
(2x + 8) / (2x + 4) = (x + 10) / (x + 7) Cross multiply
(2x + 8) (x + 7) = (2x + 4) (x + 10) Remove the brackets
2x^2 + 8x + 14x + 56 = 2x^2 + 20x + 4x + 40 Combine
2x^2 + 22x + 56 = 2x^2 + 24x + 40 Subtract right from left
-2x +16 = 0 16 from both sides
-2x = - 16 Divide by - 2
x = 8
