of her allowance on a shirt, 1/3
of her allowance on a skirt, and $8 on a belt. if she spent $22 in all, how much was carrie’s allowance?
equation

1/4a+1/3a + 8 = 22
carrie’s allowance was $

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
