We always start from right side in order of operation in any equation
we can set up equation as
step-1:
x divided by three
we can write as
[tex]=\frac{x}{3}[/tex]
step-2:
six more than x divided by three
so, we get
[tex]=\frac{x}{3}+6[/tex]
step-3:
y is six more than x divided by three
so, we get
[tex]y=\frac{x}{3}+6[/tex]
and this is in y=mx+b form
so, we have
[tex]y=\frac{x}{3}+6[/tex]...............Answer
