Question

I have a problem. Conner's age is 4 and josh's age is 12. I need to find out how many years until conner is half of josh's age and I am not sure how to put this in equation form.

Answer 1

In x years, Conner will be half of Josh's age. They are 4 and 12 respectively.

In equation form, you would do as though x is a number,
In x years, Conner will be 4+x years old, and Josh will be 12+x.
Therefore
2*(4+x) = 12+x

Answer 2

2(4+x)=12+x
8+2x =12+x
2x =4+x
x=4
