Question

solve graphicaly 2x+y= 3 and x+3y= -1​

Answer 1

Step-by-step explanation:

2x+y=3. 1 X+3y=-1 2

multiply equation 1by 3

3(2x+y)=3(3)

6x+3y=9. 3

subtact equation 3 by 2

6x+3y=9

-2x+3y=-1

=4x=8

X=8÷4

X=2

put X =2 in equation 2

x+3y=-1

2+3y=-1

3y=-1-2

3y=-3

y=-3÷3

y=-1

solutions are 2 and -1
