Question

t+10-4t=-11

Answer 1

t+10-4t=-11
10+11=4t-t
21/3=3t/3
7=t

Answer 2

Combine like terms -4t+t= -3t
you need to get 5t by itself so subtract -10 from both sides
-11- 10=-21
then divide by -3 on both sides -21/-3 the negatives cancel out and make a positive
which equals 7.
Remember whatever you do on one side you HAVE to do on the other.

Answer 3

equal to a+b-xt=-c

a+b-xt=-c
a+b+c = xt
xt = a+b+c
t = (a+b+c)/x
