Respuesta :

Answer:

22 cars & 2 trucks

Step-by-step explanation:

Let c stand for cars

Let t stand trucks

12c + 18t = 300

If we know that c is 22, then let's find t:

12(22) + 18t = 300 (first do what is in parenthesis)

264 + 18t = 300 (then combine like terms)

18t = 36 (divide to get t alone)

t = 2

Ans: They washed 22 cars and 2 trucks
