Solve 411pi=pi*129*x+pi*129^2

$$411 \pi = \pi \times 129 \times x+ \pi \times { 129 }^{ 2 }$$

Solve for x

$$x = -\frac{5410}{43} = -125\frac{35}{43} \approx -125.813953488$$

Steps for Solving Linear Equation

Calculate 129 to the power of 2 and get 16641.

$$411\pi =\pi \times 129x+\pi \times 16641$$

Swap sides so that all variable terms are on the left hand side.

$$\pi \times 129x+\pi \times 16641=411\pi$$

Subtract \pi \times 16641 from both sides.

$$\pi \times 129x=411\pi -\pi \times 16641$$

Combine 411\pi and -\pi \times 16641 to get -16230\pi .

$$\pi \times 129x=-16230\pi$$

Cancel out \pi on both sides.

$$129x=-16230$$

Divide both sides by 129.

$$x=\frac{-16230}{129}$$

Reduce the fraction \frac{-16230}{129} to lowest terms by extracting and canceling out 3.

$$x=-\frac{5410}{43}$$
