Question

solve the following pair of linear equations graphically 2x + Y is equals to 4 and 2 x minus 3 Y is equals to 12​

Answer 1

1. 2x +y =4
2. 2x - 3y= 12

subtracting 1. from 2.

2x+y=4

2x-3y=12

2(-)(+)(-)

4y = -8

y=-8/4

y=-2

put y=-2 in 1.

2x+y=4

2x+(-2)=4

2x=4+2

2x=6

x=6/2

x=3

Answer 2

point the set wise points on graph and extend the lines

u will get intersecting lines

hope u understand this

thank you
