Question

solving equations by graphing
3x+4y=8
x-3y=-6

Answer 1

woud i add the 4y and 3y together?

Answer 2

solve for x in the 2nd equation:
x = 3y-6
Plug that into eqn above:

Answer 3

3(3y-6)+4y = 8
9y - 18 + 4y = 8
13y = 8+18
13y = 26; y = 2

Answer 4

y = 2
x = 3y-6 = 6-6 = 0

Answer 5

x = 0; y = 2 Please click on become a fan if I helped! Thanks!=)

Answer 6

sorry didnt see that it was by graphing:
to solve by graphing find y in terms of x in both cases and then graph them on a calculator and ur answer will be the point where they intersect (in this case (0;2)).. I'm off to class now
