Christies average monthly expenses are $450 less than half of her monthly income. If the sum of her average monthly expenses and monthly income is $3600 what is her monthly income

Respuesta :

expenses=x
income=y
x=1/2y-450
x+ y=3600  so x=3600-y

3600-y=1/2y-450 so 4050=3/2y
1.5y=4050
y=4050/1.5 so y=2,700
since x + y=3600 and y=$2,700 then x=$900.00
