Given parallelogram WXYZ, WV = 5x - 5, and WY = 20, find the value of x. (Please note, canvas is broken so I had to rewrite it.)

we have
WV = 5x -- 5
WY = 20
and WV = 1/2 WY
So
[tex]\begin{gathered} WV=\frac{1}{2}WY \\ 5x-5=\frac{1}{2}(20) \\ 5x-5=10 \\ 5x-5+5=10+5 \\ 5x=15 \\ \frac{5x}{5}=\frac{15}{5} \\ x=3 \end{gathered}[/tex]answer: x = 3
