3t+[]h-5t+[]t+4h

if it simplifies to give t+6h

show the answer

test tomorrow god bless who can

Its just a matter of combining like terms...
3t + ?h - 5t + ? t + 4h

lets separate our t and h terms...
3t - 5t + ?tand the answer has to be 1t or just tlets simplify
-2t + ?t = 1tso -2 + ? = 1-2 + 3 = 1...so 3 is our missing t.
lets check3t - 5t + 3t = 6t - 5t = 1t or just t (correct)

?h + 4hand it has to equal 6h
so 4 + what = 6 ? 4 + 2 = 6...so our missing h is 2.
lets check2h + 4h = 6h (correct)

so ur expression is : 
3t + 2h - 5t + 3t + 4h...and when combining like terms, u end up with :
t + 6h
