Question

how do I find the values of x and y

Answer 1

From the properties of the shape (parallelogram) we have that the following is true;

$4y=6y-42$

&

$6x-12=2x+36$

Now, we solve each expression for y & x respectively, that is:

$\Rightarrow4y-6y=-42\Rightarrow-2y=-42$$\Rightarrow y=21$

&

$\Rightarrow6x-2x=36+12\Rightarrow4x=48$$\Rightarrow x=12$

So, the values of x & y are 12 & 21 respectively.
