Question

solve the following system of equal on graphically 3 X + y+1=0and 2x-3y+8=0 ??.​

Answer 1

give equation

3x+y+1=0 and 2x-3y+8=0

so in eq 1

3x+y=-1

y=-1-3x

x 0 -1 1

y 1 2 -4

similarly

in eq 2

2x-3y+8=0

2x-3y=-8

2x=-8+3y

x=-8+3y/2

x -4 -5 -1

y 0 1 2

you got the coordinates now place them in graph thank you
