0.4=(2.8x)/(0.4x^2+1.3)

Solution

0.4 = \frac{2.8 x}{0.4 x ^{2} + 1.3}

Solution

x = \frac{2.8 + 7.5072}{0.32}, x = \frac{2.8 - 7.5072}{0.32}

+1

Solution steps

0.4 = \frac{2.8 x}{0.4 x ^{2} + 1.3}

Multiply both sides by

0.4 x^{2} + 1.3

0.4 (0.4 x^{2} + 1.3) = 2.8 x

Solve

0.4 (0.4 x^{2} + 1.3) = 2.8 x : x = \frac{2.8 + 7.5072}{0.32}, x = \frac{2.8 - 7.5072}{0.32}

x = \frac{2.8 + 7.5072}{0.32}, x = \frac{2.8 - 7.5072}{0.32}
