Question

Solve the following linear in equalities graphically
x + 2y = 0,2x - y = -2, x 20, y20​

Answer 1

Step-by-step explanation:

x + 2y = 0 ------------(i)

2x - y =-2 -------------(ii)

from first equation

x=-2y

put the value of x in second equation

2x - y = -2

2 (-2y) -y = -2

-4y - y = -2

-5y = -2

y=-2/-5

similarly x value

x = -4/5
