Which equation has exactly one solution?

4x - 7 = -3(3 + 4x)
4x - 7 = 0.5 (3 + 8x)
4x - 7 = 0.5 (-14 + 8x)
-12x - 7 = -3(3 + 4x)

The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.
