Question

solve the equation in graphical method 2x+3y=2 and x_2y=8​

Answer 1

2x+3y=2

if x=7

2(7)+3y=2

14+3y=2

3y=2-14

3y=-12

y= -12

3

y = -4

(x,y) = (7,-4)

if y=4

2x+3(4)=2

2x+12=2

2x=2-12

2x=-10

x = -10

2

x = -5

(x,y) = (-5,4)

x-2y=8

if x=4

4-2y=8

-2y=8-4

-2y=4

y = 4

-2

y = -2

(x,y) = (4,-2)

if y=4

x-2(4)=8

x-8=8

x=8+8

x= 16

(x,y) = (16,4)
