To solve the equation \( 72x + 7x = 6 \), follow these steps:

### Step 1: Combine like terms
Both terms on the left-hand side involve \(x\), so we can add them together:
\[
72x + 7x = 79x
\]
The equation becomes:
\[
79x = 6
\]

### Step 2: Solve for \(x\)
To isolate \(x\), divide both sides of the equation by 79:
\[
x = \frac{6}{79}
\]

### Final Solution:
\[
x = \frac{6}{79}
\]
