Answer:
x=13/16
Explanation:
The question is asking us to isolate the variable x. This means that we need to add -3/8 to both sides of the equation. Because the denominators of the fractions 3/8 and 7/16 are not the same, we need to find a common denominator, which is 16. (So we change 3/8 to 6/16 because the two fractions are equal). Now that we have the fractions 6/16 and 7/16 we can add the two to get x=13/16
