Question

3x + 4 = y Solve the formula for x.

Answer 1

Hello!

To solve an equation for a particular variable, you must isolate the given variable on one side of the equation. We'll begin by restating the given formula:

3x + 4 = y

Now subtract 4 from both sides of the equation:

3x = y – 4

Now divide both sides by 3:

x = $\frac{y-4}{3}$

We have now proven that X is equal to $\frac{y-4}{3}$.

I hope this helps!
