Adult x Tickets
child y Tickets
1 x + 1 y = 118 .............1
9 x + 7 y = 1022 .............2
Eliminate y
multiply (1)by -7
Multiply (2) by 1
-7 x -7 y = -826
9 x 7 y = 1022
Add the two equations
2 x = 196
/ 2
x = 98
plug value of x in (1)
1 x + 1 y = 118
98 + 1 y = 118
1 y = 118 -98
1 y = 20
y = 20
Adult 98 Tickets
child 20 Tickets
