Can you explain how to do 6x - 3y 30 and 4x 2 - y then find x y?

6x-3y=30

4x=2-y

There are many ways to find the values of x and y.

elimination

substitution

matrices

on and on...

Here's one.

Set them both equal to y

y=2x-10

y=2-4x

So the right sides are both equal to y, therefore, they are equal to each other.

2x-10 = 2-4x

6x=12

x=2

plug 2 in for x on one of the equations

y=2-4x

y=2-4(2)

y=-6
