Question 334921
How to get started...
To add fractions, you need a common denominator.
You have a common denominator on the left hand side, {{{y}}} so you can add the numerators.
{{{(17+y)/y + (32+y)/y = 100}}}
{{{(17+y+32+y)/y=100}}}
Take it from there.
Next step, simplify and multiply both sides by {{{y}}}.

Your answer will look like,
{{{y=13/22}}}<--- Just an example, that's not the answer.
