The sum of \(x\) and \(3 x + 4 x\) is:

\[\begin{aligned}&=\left(x\right) + \left(3 x + 4 x\right) \\\\ &= 8 x \\\\\end{aligned}\]

The difference of \(x\) and \(3 x + 4 x\) is:

\[\begin{aligned}&=\left(x\right) - \left(3 x + 4 x\right) \\\\ &= - 6 x \\\\\end{aligned}\]

The product of \(x\) and \(3 x + 4 x\) is:

\[\begin{aligned}&=\left(x\right) \cdot \left(3 x + 4 x\right) \\\\ &= x \left(3 x + 4 x\right) \\\\ &= 7 x^{2} \\\\\end{aligned}\]

The quotient of \(x\) and \(3 x + 4 x\) is:

\[\begin{aligned}&= \frac{\left(x\right)}{\left(3 x + 4 x\right)} \\\\ &= \frac{1}{7} \\\\\end{aligned}\]
