Question

Solve for x. z=3x-4y

Answer 1

$z=3x-4y\\\\3x=4y+z\\\\x=\dfrac{4y+z}{3}$

Answer 2

First you had to switch sides of equation.

And it gave us ⇒ $3x-4y=z$

Then add by four-y from both sides of equation form.

And it gave us ⇒ $3x-4y+4y=z+4y$

Simplify.

And it gave us ⇒ $3x=z+4y$

Next, you divide by three from both sides of equation form.

And it gave us ⇒ $\frac{3x}{3}= \frac{z}{3}+ \frac{4y}{3}$

And finally, simplify.

And it gave us ⇒ $x=\frac{z+4y}{3}$

Final answer is ⇒ $\boxed{x=z+4y/3}$

Hope this helps!
