7%2F%283x%2B4%29=x%2B1
%283x%2B4%29%28x%2B1%29=7
3x%5E2%2B3x%2B4x%2B4=7
3x%5E2%2B7x-3=0
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-7+%2B-+sqrt%28+7%5E2-4%2A3%2A%28-3%29+%29%29%2F%282%2A3%29+
x+=+%28-7+%2B-+sqrt%28+49%2B36+%29%29%2F%286%29+
highlight%28x+=+%28-7+%2B-+sqrt%28+85%29%29%2F%286%29%29+
