x = \frac{51}{5}

Decimal Notation

x = 10.2

Solution steps

\frac{1}{3} + \frac{4}{5} = \frac{x}{9}

Switch sides

\frac{x}{9} = \frac{1}{3} + \frac{4}{5}

Simplify

\frac{1}{3} + \frac{4}{5} : \frac{17}{15}

\frac{x}{9} = \frac{17}{15}

Multiply both sides by

9

x = \frac{51}{5}

x + 5 = 4 x - 1

y, 4 x - 1 = 3 y + 5

2 d + 3 = 9

a, b^{2} - 4 a c = 0

13 + \frac{x}{4} = x + 1
