Question

Solve the following simultaneous equations graphically
x+y=6;x-y=4

Answer 1

x=5 y=1 this is a answer

Answer 2

Answer:

Solution of x+y=6;x-y=4 is (5,1)

i.e. x= 5 and y=1

Step-by-step explanation:

To solve the following simultaneous equations graphically

x+y=6;x-y=4

first find two-2 points; x and y intersect by putting y= 0 and x= 0 respectively

1) x+y = 6

when x= 0,y= 6 ;point (0,6)

when y= 0,x= 6; point(6,0)

Now join these points to form a straight line(green color line in graph attached)

1) x-y = 4

when x= 0,y= -4; point (0,-4)

when y= 0,x= 4; point(4,0)

Now join these points to form a straight line(Red color line in graph attached)

Intersection of these two lines are solution of equations.

Hope it helps you.
