A= adult ticket c=child ticket
1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)

Answer:
5X²+16X+8=0
Step-by-step explanation:
5(X+2) (X+2)=4(X+3)
5(X²+2X+2X+4)=4(X+3)
5(X²+4X+4)=4(X+3)
5X²+20X+20=4X+12
5X²+20X-4X+20-12=0
5X²+16X+8=0
