Solve the system of equations by elimination or substitution

Solve the system of equations by elimination or substitution:

-7x-4y=22

-9x-2y=0

-7x -4y =22

-9x -2y=0

multiply equation second by -2 and add it to equation first,

-7x -4y+18x +4y=22-0

11x=22

x=2

Substituting back the value of x

-7(2)-4y=22

-4y=22+14

y=-9

Solution is (2,-9)
