49 x^{2} = 81

x = \frac{9}{7}, x = - \frac{9}{7}

Decimal Notation

x = 1.28571 \dots, x = - 1.28571 \dots

Solution steps

49 x^{2} = 81

Divide both sides by

49

x^{2} = \frac{81}{49}

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = \frac{81}{49}, x = - \frac{81}{49}

\frac{81}{49} = \frac{9}{7}

- \frac{81}{49} = - \frac{9}{7}

x = \frac{9}{7}, x = - \frac{9}{7}

100 x^{2} = 64

\frac{10 x + 1}{2} = \frac{9}{2}

x + \frac{1}{3} (x - 3 - \frac{1}{2} (4 - 3 x)) = \frac{2}{3} (1 - \frac{5 x}{2})

\frac{3}{3 15}

∣ 3 x - 4 ∣ = 12
