Question 950136: Please help me solve this word problem: "Jim and James are brothers. Jim's age is seven less than two times James' age. Their combined age is forty-one. How old are James and Jim?"
I have tried to set up many equations, which includes 2x-7+x=41, where the variable "x" would equal James' age, but this has not worked.
Thank you.

x, Jim's age
y, James age
-

Jim's age is seven less than two times James' age.
x=-7%2B2y



Their combined age is forty-one.
x%2By=41


SYSTEM OF EQUATIONS

system%28x=-7%2B2y%2Cx%2By=41%29

Substitute x into the age sum equation,
%28-7%2B2y%29%2By=41
Simplify,
2y-7%2By=41
2y%2By-7=41
3y-7=41
3y=41%2B7
3y=48
highlight%28y=48%2F3=16%29

x=2y-7
x=2%2A16-7
x=32-7
highlight%28x=25%29


YOUR equation should still work, no matter which way James and Jims variables were assigned. Your starting equation is good according to how you assigned x for James age. You would get the y value for Jims age.

***
x=james' age
2x-7=jim's age
2x-7+x=41
3x=48
x=16
2x-7=25
james' age=16
jim's age=25
Nothing wrong with your equation. You are right on track!
