Solve 2700=xx0.8x

$$2700 = xx0.8x$$

Solve for x_0

$$x_{0}=\frac{3375}{x^{2}}$$

$$x\neq 0$$

Steps for Solving Linear Equation

Multiply x and x to get x^{2}.

$$2700=x^{2}x_{0}\times 0.8$$

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

$$x^{2}x_{0}\times 0.8=2700$$

The equation is in standard form.

$$\frac{4x^{2}}{5}x_{0}=2700$$

Divide both sides by 0.8x^{2}.

$$\frac{5\times \frac{4x^{2}}{5}x_{0}}{4x^{2}}=\frac{5\times 2700}{4x^{2}}$$

Dividing by 0.8x^{2} undoes the multiplication by 0.8x^{2}.

$$x_{0}=\frac{5\times 2700}{4x^{2}}$$

Divide 2700 by 0.8x^{2}.

$$x_{0}=\frac{3375}{x^{2}}$$

Solve for x (complex solution)

$$x=-15\sqrt{15}x_{0}^{-0.5}$$

$$x=15\sqrt{15}x_{0}^{-0.5}\text{, }x_{0}\neq 0$$

Solve for x

$$x=15\sqrt{\frac{15}{x_{0}}}$$

$$x=-15\sqrt{\frac{15}{x_{0}}}\text{, }x_{0}>0$$
