Answer:
Step-by-step explanation:
a = adult cost
c = child cost
a = c + $3
200a + 100c =$2100
^ each # of tickets sold
200(c+3) + 100c =$2100
200c + 600 + 100 c = 2100 combine like terms
300c + 600 = 2100 need variable only on one side of equal sign so you subtract 600 from each side of the = sign
300c = 1500 now divide by 300 on both sides to isolate variable
c = $5

Let x and x+1 be the two consecutive integers.
Then their sum is x + (x+1) = 2x + 1.
6x + 2y = 18
2y = -6x + 18
y = -3x + 9
