$$\begin{array}{rlll}
2y-5\times 4&=&44 \qquad &\mbox{First you simplify the sides seperately }\\
2y-20&=&44 \qquad &\mbox{next you will need to get rid of the 20 } \\
2y-20+20&=&44+20 \qquad &\mbox{Now simplify again }\\
2y&=&64 \qquad &\mbox{Next you need the y by itself so get rid of the 2 }\\
2y\div 2&=&64\div 2 \qquad &\mbox{Simplify again }\\
y&=&32 \qquad &\mbox{ }\\
\end{array}$$

 

Just remember: What ever you do to one side you must also do to the other side. the equation must stay  balanced.
