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
