Question

Y=6x - 11 -2x - 3y = -7

Answer 1

Therefore x=2 and y= 1

Explanation:

Given equations are

`y = 6x -11` and
`-2x -3y = -7`.........(2)

⇒
`y - 6x = -11`.......(1)

Equation (2)× 3 - Equation (1)

`-6x -9y -(y-6x) = -21 -(-11)`

⇔
`-6x -9y-y+6x=-21+11`

⇔-10y = -10

⇔y=1

Putting the value of y in equation (1) we get

`1 = 6x -11`

⇔x =2

Therefore x=2 and y= 1
