Question

Solve using any method. −2x+y=3 −3x+y=1 (-1, -2) (2, 7) (-2, -1) (-2, -5)

Answer 1

Therefore the Final Solution is x = 2 and y = 7

i.e (2 ,7)

Explanation:

Given:

`-2x+y=3` ...............Equation ( 1 )

`-3x+y=1` ...............Equation ( 2 )

`y=3x+1` ..............Equation ( 3 )

To Find:

x = ?

y = ?

Solution:

Substituting Equation ( 3 ) in Equation ( 1) we get

`-2x+3x+1=3\\\\x=3-1\\\\\therefore x =2`

Now Substituting x = 2 in Equation ( 3 ) we get

`y=3* 2+1=6+1\\\\\therefore y=7`

Therefore the Final Solution is x = 2 and y = 7

i.e (2 ,7)
