Question

Which of any of these Equation shows the relationship between Kevin's age x and his mothers age Y choose all that are correct 3x-y=1 y-3x=1 3x+1=Y 3x=1-y

Answer 1

Answer:

b) y-3x = 1

c) 3x+1 = y

Step-by-step explanation:

I think you forgot to write a little part of the question. If your complete statment with this condition, i have the answer.

"Kevin said that if you triple his age the result will be 1 less than his mother age. Which of any of these Equation shows the relationship between Kevin's age x and his mothers age Y choose all that are correct

a) 3x-y=1

b) y-3x=1

c) 3x+1=Y

d) 3x=1-y"

you can write "the triple of this ages" as: 3x. and the result is y-1. That is:

3x = y-1

That equation can be rewrite as:

1. Passing -1 to the other side as +1 you will have: 3x+1=y. That is option c).

2. From last point  3x+1=y. Passing 3x to the other side as -3x you will have: y-3x=1. That is option b).
