Question

Can you Find the solution of the system of equations?

Answer 1

x = 3

y = 2

Explanation:

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

`7x-7y=7\\4x+7y=26`

`11x=33`

`x=33/11`

`x=3`

"y" is calculated:

`7(3)-7y=7`

`21-7y=7`

`-7y=-14`

`y=(-14)/(-7) =2`

Hope this helps
