    Ok so your original equation is \[Y=\frac{ 1 }{ 4 }x +8\]

    First, we plug in 20 for x \[Y=\frac{ 1 }{ 4 }(20)+8\]

    Since all whole numbers have a denominator of 1, we can multiply them together.\[\frac{ 1 }{ 4 } \times \frac{ 20 }{ 1 }\] To do this, you can simply just multiply 1 by 20, and 4 by 1

    Now we get \[Y= \frac{ 20 }{ 4 }+8\] To finish solving, do \[20\div4=5\] and then add 8. 8+5=13
