Question 324922: Find all of the errors in the following solution to an
equation.
7/x=8/(x+3)+1

7(x+3)=8x+1

7x+3=8x

-x=-3

x=3

um that entire problem was worked out incorrectly view process below:
7%2Fx=8%2F%28%28x%2B3%29%2B1%29
7%2Fx=8%2F%28x%2B4%29
8x=7%28x%2B4%29
8x=7x%2B28
x=28


if this wasnt the correct set up then please write the correct probem


could also be this:
7%2Fx=%288%2F%28x%2B3%29%29%2B1
7%2Fx=%288%2F%28x%2B3%29%29%2B%28%28x%2B3%29%2F%28x%2B3%29%29
7%2Fx=%288%2B%28x%2B3%29%29%2F%28x%2B3%29
7%2Fx=%28x%2B11%29%2F%28x%2B3%29
%28x%28x%2B11%29%29=%287%28x%2B3%29%29
%28x%5E2%2B11x%29=%287x%2B21%29
x%5E2%2B4x-21=0
%28x%2B7%29%28x-3%29=0
x=-7,3
