Question

4x-2y=10
y=-2x-1
Find the solution

Answer 1

Therefore the Final Solution is

`x = 1\\ and\\ y = -3`

Explanation:

Given:

`4x-2y=10` ...............Equation ( 1 )

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

To Find:

x = ?

y = ?

Solution:

Substituting Equation ( 2 ) in Equation ( 1 ) we get

`4x-2(-2x-1)=10\\4x+4x+2=10\\8x=8\\x=(8)/(8)=1\\\\\therefore x =1`

Now Substituting x = 1 in Equation ( 2 ) we get

`y=-2(1)-1=-2-1=-3\\\therefore y=-3`

Therefore the Final Solution is

`x = 1\\ and\\ y = -3`
