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 = [tex] \frac{y-4}{3} [/tex]
We have now proven that X is equal to [tex] \frac{y-4}{3} [/tex].
