Step-by-step explanation: To find this, first convert 1/2 to fourths by multiplying by 2/2. This should get you 2/4. Add 2/4 to both sides to cancel out 1/2. This gets you h=5/4 which can be simplified to 1 1/4.
First, you need to go backwards. Instead of subtracting, add 1/2 to 3/4. Since they don't have the same denominator, change 1/2 into 2/4. 2/4 + 3/4 = 5/4. So, h is equal to 5/4. You can also check this just in case by filling in 5/4 to h. 5/4-1/2=3/4.
