Question

Y=2x+ 2 y=x-1 how many solutions does the system of equations have​

Answer 1

Answer below

x = -3

y = -4

Step-by-step explanation: First put the first equation in standard form and put the second equation in for y. 2x -1y = -2. 2x -1(x-1) = -2.

2x -1x + 1 = -2

1x+1=-2

1x = -3

x = -3

Put x (which is -3) back into the first equation originally before standard form(y=2x+2) to get y = 2(-3) + 2.

Which is -6+2=-4

so x = -3

and y = -4.

Hope this helps! :)
