3=-7+sqrt4x

Answered by GPT-5 mini AI
Interpretation 1 (most likely): 3 = -7 + √(4x)

1. Isolate the square root: √(4x) = 3 + 7 = 10
2. Square both sides: 4x = 100
3. Solve: x = 25

Check domain: 4x ≥ 0 ⇒ x ≥ 0, and √(100) = 10 so the solution x = 25 is valid.

Note: If you meant √4 · x = 2x (i.e., the square root of 4 times x), then
3 = -7 + 2x ⇒ 2x = 10 ⇒ x = 5.
