Solve the system of equations below by graphing both equations with a pencil and paper. y = -3 + 1 and y = -x + 5

(-2,7)

Step-by-step explanation:

y=-3x+1  which is equivalent to y+3x=1

y=-x+5  which is equivalent to y+x=5

subtract the two equations :

y+3x-(y-x)=1-5

2x=-4

x=-2

substitute x in one equation : y+(-2)=5

y=5+2=7

check :

y+x=5

7-2=5

y+3x=1

7-6=1
