we solve for y doing operations on both sides
we remove 3x of left side subtractinc 3x on both sides
[tex]\begin{gathered} 3x-3x-7y=22-3x \\ -7y=22-3x \end{gathered}[/tex]then we divide between -7 to solve y
[tex]\begin{gathered} \frac{-7y}{-7}=\frac{22-3x}{-7} \\ \\ y=\frac{-22+3x}{7} \\ \end{gathered}[/tex]we can rewrite the equation to obtain the form y=mx+b
[tex]y=\frac{3}{7}x-\frac{22}{7}[/tex]
