Question

3=2x+y solve this equation ​

Answer 1

Answer:

Hey there !

Solution:

2x + y = 3

=> y = 3 - 2x

So let us get all the values,

If x = 1, y = ?

=> y = 3 - 2 ( 1 )

=> y = 3 - 2 = 1

Hence first Coordinate is ( 1,1 )

If x = 2, y = ?

=> y = 3 - 2 ( 2 )

=> y = 3 - 4

=> y = -1

Hence second coordinate is ( 2,-1 )

If x = 0, y = ?

=> y = 3 - 2 ( 0 )

=> y = 3 - 0

=> y = 3

Hence third coordinate is ( 0,3 )

Hence plotting these points on graph and joining them by a single straight line, we get,

Hope my answer helped !

Answer 2

Answer:

3=2x+y

If x =0

3=2(0)+y

3=0+y

y=3

3=2x+y

If y =0

3=2x+0

2x=3

x=3/2
