Question

Find the solution to these systems of equations:

4x+7y=3
4x-y=-5

Answer 1

subtract one equation from the second. that will give you a y. substitute that in any of the two, you will get an x.

Answer 2

so like the 4x-4x and 7y-y and 3-5?

Answer 3

that will be 4x- (4x) and 7y-(-y) and 3-(-5).
