13= 5/2 (5x+4)

13 = \frac{5}{2} (5 x + 4)

x = \frac{6}{25}

Decimal Notation

x = 0.24

Solution steps

13 = \frac{5}{2} (5 x + 4)

Switch sides

\frac{5}{2} (5 x + 4) = 13

Multiply both sides by

2

5 (5 x + 4) = 26

Divide both sides by

5

5 x + 4 = \frac{26}{5}

Move

4

to the right side

5 x = \frac{6}{5}

Divide both sides by

5

x = \frac{6}{25}

- 16 x^{2} + 10 x + 15 = 0

\frac{2}{11} (x - 4) < 3

x^{5} y^{3} + x^{4} y^{4}

- 16 x^{2} + 24 x + 16 = 0

(\frac{x}{y ^{\frac{1}{2}}} + \frac{y ^{\frac{1}{2}}}{x})^{5}
