Add both amounts together but both multiplied by an unknown value, x.
3x+5x=600
8x=600
8x/8=600/8
x=75
3(75)=225
225 boys
5(75)=375
375 girls
225 boys and 375 girls
1+1=2 good luck so have a good day
7.5a+3c=663
a+c=113
Write a literal equation for c using the second equation.
c=-a+113
Substitute the value of c into the first equation
7.5a+3(-a+113)= 663
7.5a-3a+339=663
4.5a+339=663
4.5a=324
a=72
Final answer: 72 adult tickets sold
Check by finding the value of c and plugging both values in
(72)+c=113
c=41
7.5(72)+3(41)
663
