First you had to switch sides of equation.
And it gave us ⇒ [tex]3x-4y=z[/tex]
Then add by four-y from both sides of equation form.
And it gave us ⇒ [tex]3x-4y+4y=z+4y[/tex]
Simplify.
And it gave us ⇒ [tex]3x=z+4y[/tex]
Next, you divide by three from both sides of equation form.
And it gave us ⇒ [tex]\frac{3x}{3}= \frac{z}{3}+ \frac{4y}{3}[/tex]
And finally, simplify.
And it gave us ⇒ [tex]x=\frac{z+4y}{3}[/tex]
Final answer is ⇒ [tex]\boxed{x=z+4y/3}[/tex]
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
