Answer:
- Let x and y represent the amounts spent on accessories and clothes, respectively
- x + y = 56 . . . or y = -x + 56
- y - x = 18 . . . or y = x + 18
Explanation:
With the variables defined as above, the total amount spent is ...
x + y = 56 . . . . . the amount spent on accessories and clothes
When the amount spent on accessories is subtracted from the amount spent on clothes, the result is $18, so we can write another equation that says this:
y - x = 18
Both equations can be rearranged to put y alone on the left. In the first case, we add -x to both sides of the equation. In the second case, we add x to both sides of the equation.
