$M=W^{\text{'}}x{Y}^{\text{'}}+Wx{Y}^{\text{'}}+x{Y}^{\text{'}}Z$ using Boolean

properties to show that $M=x{Y}^{\text{'}}.$ Show your work.

$f=xy+w^{\text{'}}{y}^{\text{'}}z+w^{\text{'}}x{y}^{\text{'}}+wxy{z}^{\text{'}}+w^{\text{'}}yz+wz$

$($Hint: the minimal expression is $3$ terms with $5$ literals$)$
