You should learn to check your own work. Here's how:
Substitute x=3 and y=2 into each of the two equations:
7x-4y = 13 | 3x+y = 11
7(3)-4(2) = 13 | 3(3)+(2) = 11
|
Do the operations | Do the operations
on the left side | on the left side
and see if you get: | and see if you get:
|
13 = 13 | 11 = 11
If you do get that in both cases, then you'll know your answer
is correct. If you don't get that in either case you will know
that you made a mistake.
