    What is the value of the x variable in the solution to the following system of equations? 3x + 2y = 8 2x + 3y = 2 4 –2 x can be any number as there are infinitely many solutions to this system. There is no x value as there is no solution to this system.

    Multiply the first equation by 3, what do you get?

    No? Multiply both sides of the first equation by 3: 3 (3x + 2y) = 3 (8) ^Simplify this

    How do you get 4 from doing the multiplication?

    i was guessing the answer

    Perhaps we can solve it together, rather than just guessing it?

    Let see how it goes :) First, multiply both sides of the first equation by 3, we get 3 (3x + 2y) = 3 (8) 9x + 6y = 24 Do you get this part so far?

    Just call that equation (9x + 6y = 24) as (a) Now, we multiply the second equation 2x + 3y = 2 by 2, what do you get?

    wait what's y?

    We will calculate it if you want. But in this case, we are going to solve the system of equations by elimination. And the variable we are going to eliminate is y.

    Actually, we'll get the answer quite soon... A few more steps to go :| What do you get when you multiply the second equation 2x + 3y = 2 by 2?

    10 for the answer or is that what you get when you do the multiplication?
