Right and solve an equation using X as the variable to represent the situation. After Carlos spent $18, he saw he had $20 left. How much more money did Carlos have to start?

X - 18 = 20

Step-by-step explanation:

After writing the equation, add 18 to both sides. You'll end up with an equation of X = 38. Hope this helps

x = 20 + 18

Step-by-step explanation:

The variable 'x' represents the amount of money Carlos had before he spent the $18. If he spent $18 but still had $20 left, that would mean he would have $38.

x = 38

there will be 35 boys in each team. : )
