Answer:
x =25
Step-by-step explanation:
Set it up like this
15/3 = x/5 You could cancel or you could cross multiply. We'll do both.
Cancel
15/3 = 5
5 = x/5 Multiply both sides by 5
5*5 = x Combine
25 = x
Cross Multiply
15/3 = x/5 Cross multiply
15 * 5 = 3 * x Combine the left
75 = 3x Divide both sides by 3
75/3 = 3x/3 Do the division
25 = x Answer
