Question 246893
3x + 4y = 5
2x + 3y = 4 
Solve this problem using elimination.

If we multiply both sides of the first equation by 2 and both sides of the second equation by 3 we have:

6x + 8y = 10
6x + 9y = 12

We did this so we would have the same coefficient on x (that is 6). So now we can subtract the second equation from the first eliminating x:

(6-6)x +(8-9)y = 10-12
(0)x + (-1)y = -2
-y = -2
y = 2

Now substitute y=2 in either of the original equations and solve for x.
