Question

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

Answer 1

x= -1 y=3

Explanation:

Answer 2

x = -1

y = 3

Explanation:

2x +y =1 3x -y= -6

Add the two equations together to eliminate y

2x +y =1

3x -y= -6

------------------

5x = -5

Divide by 5

5x/5 = -5/5

x = -1

2x+y = 1

2(-1) +y = 1

-2 +y =1

Add 2 to each side

y = 1+2

y =3
