j = coach johnson's age t = tim's age Coach Johnson is 10 years older than Tim j = t + 10 When Tim started football 3 years ago, Coach Johnson was twice his age t - 3 = (j - 3)/2 And then you have simultaneous equations. j = t + 10 t - 3 = (j - 3)/2 Good luck.
idk why but i cant solve it.
Okay, how about use substitution. You know from that first equation what j is; j = t + 10 replace j with (t + 10) in the second equation. so instead of t - 3 = (j - 3)/2 you have t - 3 = ((t + 10) - 3)/2 Now solve for t and you can find out what t is.
