2x+7y=-6
4x-y=18\
show step by step how it is solved

(60/13, 6/13)

Concept:

There are three general ways to solve systems of equations:

Here, we are going to use elimination since all the variables are in the corresponding position.

Solve:

Given

Multiply the first equation in order to eliminate [x]

Subtract the second equation from the first equation to eliminate [x]

Divide 13 on both sides

Substitute [y] value in order to get [x] value

4x - y = 18

4x - 6/13 = 18

4x = 18 + 6/13

4x = 240/13

Hope this helps!! :)
