Question

the point of intersection of 2x+y=20 & x+3y=24 is ​

Answer 1

Answer:

2x+y=20

2x=20-y

x=20/2

X=10 ans

and

x+3y=24

3y=x-24

y=24/3 ans

Answer 2

Answer:

the point of intersection is (36/5 , 28/5)

Step-by-step explanation:

2x + y = 20                                             -----(1)

x + 3y = 24 --( x 2)   2x + 6y = 48          -----(2)

by subtracting these two equation we get,

-5y = -28

y = 28/5

apply value of y in equation 1

2x + 28/5 = 20

2x = 20 - 28/5 = (100 - 28)/5 = 72/5

x = 36/5

therefore x=36/5, y=28/5

so, the point of intersection is (36/5 , 28/5)
