Question

Solve the system of equations using algebra.
5c -4t=8
14 +4t= 3c

Answer 1

Addition or Substitution?

Answer 2

elimination or substitution is what im guessing you mean.

Answer 3

i use substitution.

Answer 4

yes, my bad.

Answer 5

Ok, then you have to set one of the equations as x=... or y... first.

Answer 6

I would use elimination though, see how -4t and 4t are there already for you to add?

Answer 7

the answers i got at the end were t= 15/11 and c= 40/11

Answer 8

but i dont think they are right

Answer 9

if you use elimination, you need to set up the 2nd equation just like the first one by subtracting 3c and subtracting 14

Answer 10

how would you do it withe elimination?
