Hey, so I have this equation here which is: Find the intersection of 4y - 3x = 5 and 3x - 2y = 4


I been wrecking my brain with this but i do not know the process of being able to show this on paper.
Is anyone able to show me a step by step procedure for me to be able to right this equation down and find the intersecting point.
Cheers

You could go to the following link here as suggested, and it will work for sure,
but there will be fractions in each equation after you solve each equation for y.

As an alternative, you could rewrite the second equation as\(\displaystyle \ \) -2y + 3x = 4, place it under
the first equation, and add the two equations. The x-terms will cancel out, and you can
solve for the y-variable first, before later substituting back for the x-variable.



\(\displaystyle \ \ \ 4y \ - \ 3x \ = \ 5\)
\(\displaystyle -2y \ + \ 3x \ = \ 4\)
----------------
\(\displaystyle \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \) <---------- What resulting equation goes here?


Continue.
