Answer:
x = 1/8
Step-by-step explanation:
The first step is to make all of the denominators in the fractions the same. To do so, find what number multiplies by 4 to get to 8. This number is 2. Then, multiply that number to the numerator of the fraction you're going to change.
3/4 becomes 6/8.
The equation becomes 6/8 + x = 7/8.
Now, pay attention to the numerators. What number adds to 6 to get to 7? The answer is 1. Remember, the denominators must be the same, so the final answer is x = 1/8.
