1/7+4(3)+1/7-4(3)

To simplify the expression \( \frac{1}{7} + 4(3) + \frac{1}{7} - 4(3) \), we can break it down step by step.

1. Calculate \( 4(3) \): \[ 4(3) = 12 \]

2. Substitute this back into the expression: \[ \frac{1}{7} + 12 + \frac{1}{7} - 12 \]

3. The \( +12 \) and \( -12 \) cancel each other out: \[ \frac{1}{7} + \frac{1}{7} = 2 \times \frac{1}{7} \]

4. Now, compute \( 2 \times \frac{1}{7} \): \[ 2 \times \frac{1}{7} = \frac{2}{7} \]

Thus, the simplified expression is: \[ \frac{2}{7} \]
