Answer:
The variables are:
x = 7
y = 10
Explanation:
The opposite sides of a parallelogram are equal.
We can use the above statement to find the variables in the given parallelogram as follows:
[tex]\begin{gathered} 9y+7=10y-3 \\ 10y-9y=7+3 \\ y=10 \end{gathered}[/tex]
Similarly,
[tex]\begin{gathered} 12x-1=10x+13 \\ 12x-10x=13+1 \\ 2x=14 \\ x=\frac{14}{2}=7 \end{gathered}[/tex]
