Answer by JKismyhusbandbae:
[tex]\frac{x}{4}=20\\\mathrm{Multiply\:both\:sides\:by\:}4\\\frac{4x}{4}=20\cdot \:4\\Simplify\\x=80[/tex]
remember that you can do anything to an equaiton as long as you do it to both sides
x/4=20
multiiply both sides by 4
4(x/4)=20*4
(x)(4)(1/4)=80
(x)(4/4)=80
x(1)=80
x=80
