What is the solution of 7x-6y=-16

8x-6y=-20

We can multiply the first equation by - 1 then add it to the 2nd equation:

7x - 6y = - 16

-7x + 6y = 16

-7x + 6y = 16

8x - 6y = - 20

x + 0 = - 20

x = - 4

So our x-value is - 20, we can plug this into any of the two equations to get the y-value:

8x - 6y = - 20

8 (-4) - 6y = - 20

-32 - 6y = - 20

Add 32 to both sides:

-6y = 12

y = - 2

So our final answer is (-4, - 2).
