Question

Show that (1, 5) as well as (-2, −1) are the solutions of the equation 2x − y + 3= 0. Find two more solutions. How many solutions can we find?

Answer 1

Answer:

ANSWER

2x−3y+17=0⇒2x=3y−7⇒x=

2

3y−7

at y = 1 x = -2

at y = -1 x = -5

so (-2, 1) (-5, -1)are the 2 solution

I hope it's help you

and please give me one thanks
