Step-by-Step Simplification & Solution

Simplifying the equation means transforming it into a form where x is isolated on one side. Here’s how:

Step 1: Subtract 6 from Both Sides

To isolate the term with x, eliminate constants first. Subtract 6 from both sides:

$$
3x + 6 - 6 = 90 - 6
$$
$$
3x = 84
$$

Step 2: Divide Both Sides by 3

Now divide both sides by 3 to solve for x:
