Question

solve thelinear equation graphically x-y=4 and x+y=36​

Answer 1

Step-by-step explanation:

x=4+y. put in x+y=36

4+y+y=36

4+2y=36

2y=36-4

2y=32

y=16

put y in x-y=4

x=4+16

x=20

Answer 2

Step-by-step explanation:

x-y=4 (1)

x+y=36 (2)

by using eq.1

x-y=4

x=4+y (3)

putting value of x from eq.3 in 2

x+y=36

4+y +y = 36

2y=36-4

2y=32

y=32÷2

y=16

putt value of y in eq. 1 to find x

x-y=4

x-16=4

x=4+16

x = 20

so y =16 and x = 20

to solve graphically make a graph with x axis and y axis and mark from 0 to 20 on both axis and then mark 16 on y axis and 20 on x axis
