Answer:
Nine
Step-by-step explanation:
3 dollars for children tickets : x
5 dollars for adult tickets: y
Equation is:
3x+5y=57
Where 57 is the total amount spent
x+y=15
where 15 is the total number of tickets bought
3x+5y=57
5(x+y)=5(15)
___________________
3x+5y=57
5x+5y=75
minus the equations top to bottom=
-2x= -18
x= -18/(-2)
x=9

Answer:
x = 0.5
Step-by-step explanation:
First, distribute -4 to the parentheses:
-14 = -4(9x - 1)
-14 = -36x + 4
Subtract 4 from both sides:
-18 = -36x
Divide each side by -36
0.5 = x
x = 0.5
