Question

word problem help please? (anyone above geometry)

Answer 1

Coach Johnson is 10 years older than Tim. When Tim started football 3 years ago, Coach Johnson was twice his age. How old is Tim now?

Answer 2

\[J = T+10 \\
J-3 = 2(T-3) \Rightarrow J=2T-3\]So we have:\[
J=T+10 \\
J=2T-3\]

Answer 3

so i need to solve j =2t-3?

Answer 4

?

Answer 5

It's a system of equations. Do you know how to solve these? You can also read it as:

"Johnson is 10 years older than Tim"
and
"Johnson is 3 less than twice Tim's age"

If that isn't working for you, just set \(T+10=2T-3\) and solve for\(T\).
