Question

Solve the following Simultaneous equations
graphically
3x - y-2=0; 2x + y = 8​

Answer 1

Answer:

Step-by-step explanation:

3x-y-2=0 ....(1)

2x+y=8 ....(2)

3x-y=2 ( from 1 ) ..(3)

adding equation 2 and 3

2x+y=8

3x-y=2

ans : 5x=10

x=10 ÷5

x=2

substituting x=2in equation 2

2x+y=8

2(2)+y =8

4+y =8

y=8-2

y=6

(x, y) (2,6)

Answer 2

Answer:

hope it will help you.

Step-by-step explanation:

let's first write the equation in proper way.

3x - y =2; 2x+y=8

following are the ordered pairs.(i.e). (x,y)

3x - y = 2: (1,1) (2,4) (0,-2)

2x + y = 8: (3,2) (2,4) (5,-2)

each points on the graph satisfied the equation.

The two lines intersect each other at (2,4).

The solution of given equation

3x - y - 2 = 0; 2x + y = 8 is X=2 and Y = 4.
