Question

solve graphically: X+Y=7 : X-Y =7​

Answer 1

Answer:

X = 7 , Y = 0

Step-by-step explanation:

let assume equation 1

and 2

than solve this problem

you can get you answer

Answer 2

Answer:

The solution is x = 5 and y = 2

Step-by-step explanation:

Equation 1 : x+y=7x+y=7

Equation 2: x-y=3x−y=3

Plot the given lines on graph

x+y=7x+y=7 --- Blue line

x-y=3x−y=3 --- Green line

Intersection point will provide the solution to this system of equation

Intersection point = (5,2)

hence the solution is x = 5 and y = 2
