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.
