Select all the equations that are equivalent to 1/2(4+8x) = 17

I don't think you gave the options, but I can simplify and solve it.

1/2(4 + 8x) = 17

2 + 4x = 17

If you want it simplified: 2 + 4x = 17

Subtract 2 from each side:

2 - 2 + 4x = 17 - 2

4x = 17 - 2

4x = 15

Divide each side by 4:

4x ÷ 4 = 15 ÷ 4

x = 3 and 3/4

If you want to solve for x: x = 3 and 3/4

answer: .64
