What is the solution to this system of linear equations? 2x + y = 1 3x – y = –6

From the first equation:
y = 1 - 2x

Then you can substitute that into the second equation:
3x - (1 - 2x) = - 6
3x - 1 + 2x = - 6
5x = -5
x = - 1

Since you know x, you can find y using the equation y = 1 - 2x

y = 1 - 2(-1)
y = 1 + 2
y = 3

Therefore x = - 1 and y = 3
