Question

Kevin said that if you triple his age the result will be 1 less than his mother age

Which if any of these equations shows the relationship between Kevin's age x and his mothers age y? Choose all the correct

1.) 3x-y=1

2.) y-3x=1

3.) 3x+1=y

4.) 3x= 1-y

Btw the (-) <-- subtract

Answer 1

Basically, this problem is saying that if you multiply x by 3, then you will get a number that is one less than y. So, if you switch that around a bit, then the problem is saying that if you subtract 3x from y, you'll get 1.

Your final answer should be y - 3x = 1.
