Question 667794: Extremely bad at math.
3/2 (5x + 7) = 16
3/2 * 2/3 (5x+7) = 16 * 2/3
5x+7=48/2
16 2 48
(--*-- = --- )
1 3 2
5x+7=48/2
Simplify
5x+7=24
-7 -7
---------
5x=17
17/5=3.4
Is that correct/

Hi

3/2 (5x + 7) = 16 

%283%2F2%29+%2A+%282%2F3%29+%285x%2B7%29+=+16+%2A%28+2%2F3%29   || Good Work!

    5x + 7 = 32/3         ||****

       5x = 32/3-21/3

        5x = 11/3

         x = 11/15

check you answer.
3%2F2(5(3.4)+7) = 3%2F2(17+7) = %283%2F1cross%282%29%29%2812cross%2824%29%29 = 36
not correct
...
3%2F2(5x+7) = 16
...
3%2F22%2F3(5x+7) = 162%2F3
5x + 7 = 32%2F3 *** You erred only here where you have 5x+7=highlight%2848%2F2%29. Appears you multiply 163%2F2 instead of 162%2F3.
...
Multiply both sides by 3
15x + 21 = 32
...
15x = 32 - 21
...
15x = 11
highlight_green%28x+=+11%2F15%29
...
