Question

Solve the following system of equations by substitution and select the correct answer below: 4x − 6y = 28 8x − 4y = 24

Answer 1

Y=4
X=5
But I'm bad at math so you may want to double check the answers by plugging them into the equation. (One at a time)

Answer 2

Explanation:

The equations are:

`4x-6y=28` (1)

`8x-4y=24` (2)

Taking the equation(1) and then solving it to get the value of x

⇒
`4x-6y=28`

⇒
`2x-3y=14`

⇒
`x=(14+3y)/(2)`

Now, substituting the value of x in equation (2), we get

⇒
`8((14+3y)/(2))-4y=24`

⇒
`56+12y-4y=24`

⇒
`8y=-32`

⇒
`y=-4`

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

⇒
`4x-6(-4)=28`

⇒
`x=1`

Therefore, the values of x and y are 1 and -4 respectively.
