Answer:
Explanation:
Just as a hint. On this editor, you have to use brackets a lot. We cannot be certain what you mean. I'm going to interpret the question one way, but there are others.
√(5x - 7) = √(3x + 5)
Square both sides.
(√(5x - 7) )^2 = (√(3x + 5) )^2
5x - 7 = 3x + 5
Add 7 to both sides.
5x - 7 + 7 = 3x + 5 + 7
Combine
5x = 3x + 12
Subtract 3x from both sides.
5x - 3x = 3x -3x + 12
Combine
2x = 12
Divide by 2
2x/2 = 12/2
x = 6
