Question 71876
{{{7/(x-7)}}}+4={{{3/(x-7)}}}
If I am reading the problem correctly here is the answer;
First multiply each side by x-7;
(x-7)({{{7/(x-7)}}}+4)={{{3/(x-7)}}}(x-7)
{{{(7(x-7))/(x-7)}}}+4x-28=3
now cancel the x-7 on each side;
7+4x-28=3
add like terms;
4x-21=3
add 21 to both sides;
4x+ 3+21
4x=28
divide each side by 4;
x=6
