57 children tickets were sold on Saturday.
You could set this up as a system of equations.
x + y = 155
6.00x + 9.90y = 1312.20
First step is multiplying the first equation by -6 to use the elimination method.
-6.00x + -6.00y = -930
6.00x + 9.90y = 1312.20
The positive and negative 6x cancel out until you are only left with the y.
Combining them would make your equation...
3.9y = 382.2
Next you would divide by 3.9 on both sides to get the y by itself.
The result of that would be y = 98. Which means 98 adult tickets were sold. Then you would plug y into either of the equations to solve for x.

Answer: x=2
Step-by-step explanation:
Expand.
32−8x=7x+2
Add 8x to both sides.
32=7x+2+8x
Simplify 7x+2+8x7x+2+8x to 15x+215x+2.
32=15x+2
Subtract 22 from both sides.
32−2=15x
Simplify 32−2 to 30.
30=15x
Divide both sides by 15.
30/15=x
Simplify 30/15 to 2
2=x
Switch sides.
x=2
