For this Question use the substitution method.
5x+2y = $48 ------First Equation.
3x+2y = $32 ------ Second Equation
x= 48-2y/ 5 ( 48-2y divided by 5)
Put the value of x in the second equation.
3(48-2y/5)+2y = $32
(144-6y/5) + 2y = $32
Take L.C.M
144-6y+10y/5 = $32
144+4y = 32*5
144+4y = 160
4y = 160-144
4y = 16
y = 4
Now put the value of y in any equation.
5x+2(4) = $48
5x+8 = $48
5x = 48-8
5x = 40
x = 8

Answer:
Step-by-step explanation:
{2x - 3y = 13
{x + 2y = −4
⅔[2x - 3y = 13]
{1⅓x - 2y = 8⅔
{x + 2y = −4
