Question

???????????????????????????

Answer 1

Greetings!

We can substitute the variables, so we only have to solve for one, per eqaution

`x=4y`
Therefore...

`3x-2y=20`
Is also equal to..

`3(4y)-2y=20`

Solve for y.
Combine Like terms.

`12y-2y=20`

`10y=20`
Divide both sides by 10.

`(10y)/10=(20)/10`
Simplify.

`y=2`

Now we can use the value of y to solve the other equation.

`x=4y`
Is also equal to...

`x=4(2)`

Solve for x.
Combine like terms.

`x=8`

The answer would be 8,2

Hope this helps.
