Using elimination method. Using substitution will cause some fraction problems.
c- child tickets
a- adult tickets
4a + 7c = $83
5a + 6c = $90
multiply by -5
-20a - 35c = -$415
20a + 24c = $360
-11c= -$55
c = $5 child tickets
4a + 7(5)= $83
4a + 35 = $83
4a = $48
a= $12 adult tickets

Answer:
x = -117.6
Step-by-step explanation:
1/4x + 1/2 (3/4)x + 111 = x
1/4x + 3/8x + 111 = x
2/8x + 3/8x + 111 = x
5/8x + 111 = x
5/8x = -111
8/5 (5/8x= -111)
x = -117.6
