–4 + 3x = 20

1 answer

To solve the equation \(-4 + 3x = 20\), follow these steps:

  1. Add 4 to both sides to isolate the term with \(x\):

    \[ -4 + 3x + 4 = 20 + 4 \]

    This simplifies to:

    \[ 3x = 24 \]

  2. Now, divide both sides by 3 to solve for \(x\):

    \[ x = \frac{24}{3} \]

    Simplifying that gives:

    \[ x = 8 \]

So, the solution to the equation \(-4 + 3x = 20\) is \(x = 8\).
