Question 117333
{{{x / (x-2) = 7/5}}}
multiply both sides by {{{x-2}}}
{{{x = 7(x-2) / 5}}}
multiply both sides by 5
{{{5x = 7x - 14}}}
Add {{{14}}} to both sides
{{{5x + 14 = 7x}}}
subtract {{{5x}}} from both sides
{{{2x = 14}}}
{{{x = 7}}} answer
Now check answer
{{{x / (x-2) = 7/5}}}
{{{7 / (7-2) = 7/5}}}
{{{7/5 = 7/5}}}
OK
