Questions: 7x-4=31

Transcript text: $7x-4=31$

Solution

Step 1: Move the constant term to the other side

Add $ 4 $ to both sides of the equation to isolate the term with $ x $:
\[ 7x - 4 + 4 = 31 + 4 \]
\[ 7x = 35 \]

Step 2: Solve for $ x $

Divide both sides of the equation by $ 7 $ to solve for $ x $:
\[ \frac{7x}{7} = \frac{35}{7} \]
\[ x = 5 \]

$\boxed{x = 5}$
