So first we should make the first equation in the form y = .
To do this we subtract 3x from each side and get y = -3x + 1.
Then we substitute that in the second equation to get 5x - 6x + 2 = 12.
Next we will combine like terms and get -x + 2 =12.
Then we subtract 2 from each side to have -x = 10.
Finally to get x we will multiply each side by -1 with a final x of x = -10.
Next to get y, we can plug x into the first equation to have -30 + y = 1.
We add 30 to each side to get y = 31.
The solution to this system of equations is (-10, 31).
Hope this helps!
