Second equation: 228 total price includes 22dollar x adult and 15dollar x children ticket price. Write the equation: 228= 22A+15C (substitute above value for adult)
228= 22(11-C) + 15C 228= 242-22C+15C 228 - 242 = 7C 14 = 7C C= 2 (there are 2 children in the group)
-22 = - (x - 4) = -22 = -x + 4 (distribute the minus) = -26 = -x (subtract 4 from both sides) = 26 = x (divide by -1 to remove the minus from x) so, x = 26
