Question

solve the equation & 2x+y-5 =0
3х - 2y- 4=0 by graphically​

Answer 1

Answer:

2x+y-5 =0

2x+y=5. -------------(1)

3х - 2y- 4=0

3x-2y=4. ----------------(2)

equation (1)multiply by2

4x+2y=10-------(3)

addition of equation (3)&(2)

3x-2y=4

4x+2y=10

7x+0=14

x=14/7

x=2

now,

x=2 put in equation(1)

2x+y=5.

2(2)+y=5

4+y=5

y=5-4

y=1

(x,y)=(2,1)
