Question

solve the following equation graphically: x + y = 3; x - y = 7​

Answer 1

Answer:

Given :- x + y = 3; x - y = 7

to find :- solve the following equation graphically:

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
