Solve 2059=x20.5-0.5*9.8*20.5^2

$$2059=x20.5-0.5 \times 9.8 \times { 20.5 }^{ 2 }$$

Solve for x_20

$$x_{20}=8236.45$$

Steps for Solving Linear Equation

Multiply 0.5 and 9.8 to get 4.9.

$$2059=x_{20}\times 0.5-4.9\times 20.5^{2}$$

Calculate 20.5 to the power of 2 and get 420.25.

$$2059=x_{20}\times 0.5-4.9\times 420.25$$

Multiply 4.9 and 420.25 to get 2059.225.

$$2059=x_{20}\times 0.5-2059.225$$

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

$$x_{20}\times 0.5-2059.225=2059$$

Add 2059.225 to both sides.

$$x_{20}\times 0.5=2059+2059.225$$

Add 2059 and 2059.225 to get 4118.225.

$$x_{20}\times 0.5=4118.225$$

Divide both sides by 0.5.

$$x_{20}=\frac{4118.225}{0.5}$$

Expand \frac{4118.225}{0.5} by multiplying both numerator and the denominator by 1000.

$$x_{20}=\frac{4118225}{500}$$

Reduce the fraction \frac{4118225}{500} to lowest terms by extracting and canceling out 25.

$$x_{20}=\frac{164729}{20}$$
