You can put this solution on YOUR website! Simply subtract each side by 1/8.
v = 3/4 - 1/8
Because the denominators are different, you need to multiply 3/4 by 2/2. That will make the denominator change to 8.
v = 3/4(2/2) - 1/8
v = 6/8 - 1/8
v = 5/8.
Let's plug in v's value in the original equation
5/8+1/8 = 3/4
6/8 = 3/4
Reduce the left side by dividing the numerator and denominator by 2/2
6/8 div (2/2) = 3/4
3/4 = 3/4. It checks out. So v = 5/8 is the correct answer.
