4. Solve the equation step by step: 3x + 5 = 20
To solve the equation 3x + 5 = 20, we can start by isolating the variable x.
First, we subtract 5 from both sides of the equation:
3x + 5 - 5 = 20 - 5
This simplifies to:
3x = 15
Next, we divide both sides of the equation by 3 to solve for x:
\[\frac{{3x}}{{3}} = \frac{{15}}{{3}}\]
Which gives us:
x = 5
Therefore, the solution to the equation 3x + 5 = 20 is x = 5.
