lara [203]

Answer:

x+y=52
x-y=4
y=24

Step-by-step explanation:

The sum of the two costs is $52, so we can write ...

x + y = 52

The shoes cost $4 more than the jacket, so we can write ...

x - y = 4

These are your system of equations.

Subtract the second equation from the first:

(x +y) -(x -y) = (52) -(4)

2y = 48 . . . . . simplify

y = 24 . . . . . . .divide by 2

The cost of the jacket is $24.
