Answer:

x = 3

y = 2

Step-by-step explanation:

multiply by -1 the second equation and add the two equations

[tex]7x-7y=7\\4x+7y=26[/tex]

[tex]11x=33[/tex]

[tex]x=33/11[/tex]

[tex]x=3[/tex]

"y" is calculated:

[tex]7(3)-7y=7[/tex]

[tex]21-7y=7[/tex]

[tex]-7y=-14[/tex]

[tex]y=\frac{-14}{-7} =2[/tex]

Hope this helps
