Answer:
The answer to your question is 9 adults and 2 children
Step-by-step explanation:
Data
adult ticket = $22
children ticket = $15
Total people= 11
total cost = $228
Number of adults = x = ?
Number of children = y = ?
Process
1.- Write equation to solve the problem
x + y = 11 Equation l
22x + 15y = 228 Equation ll
-Solve Equation l by x
x = 11 - y Equation lll
-Substitute equation lll in equation ll
22(11 - y) + 15y = 228
-Solve for y
242 - 22y + 15y = 228
-Simplify like terms
-7y = 228 - 242
-7y = -14
y = -14/-7
y = 2
-Find x
x = 11 - 2
x = 9
2.- Conclusion
There were 9 adults and 2 children.
3ax-8a=b-18x
3ax+18x=b+8a
3x(a+6)=b+8a
3x=(b+8a)/(a+6)
x=(b+8a)/3(a+6)
3a*(b+8a)/3(a+6)=b-18*(b+8a)/3(a+6)
a(b+8a)/(a+6)=b-6(b+8a)/(a+6)
a(b+8a)=b(a+6)-6(b+8a)
ab+8a^2=ab+6b-6b-48a
ab+8a^2=ab-48a
8a^2=-48a
8a^2+48a=0
8a(a+6)=0 so a=0,-6
0=b-18x or -18x+48=b-18x
-b=-18x or 48=b
let b=18 if a =-6
