Answer:

a = 17

c = 9

Explanation:

2a + 3c = 61

3a + 5c = 96

3a = 96 - 5c (solve for 'a'. Then you can substitute)

a = 32 -
(5)/(3) c

2(32 -
(5)/(3)c) + 3c = 61 (Substitute)

64 -
(10)/(3)c + 3c = 61 (
(10)/(3) = 3
(1)/(3). So subtracting, adding a negative, leaves
(-1)/(3))

-
(1)/(3) c= -3

c = 9

2a + 3(9) = 61

2a + 27 = 61

2a = 34

a = 17
