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).
