3/5 = 3/10 d-12

\frac{3}{5} = \frac{3}{10} d - 12

d = 42

Solution steps

\frac{3}{5} = \frac{3}{10} d - 12

Switch sides

\frac{3}{10} d - 12 = \frac{3}{5}

Move

12

to the right side

\frac{3}{10} d = \frac{63}{5}

Multiply both sides by

10

3 d = 126

Divide both sides by

3

d = 42

\frac{x - 2}{4} \geq 5

(x - 2) (1 - 5 (x - \frac{1}{5})) < - 5 (x^{2} - 2)

(\frac{a}{b})^{- 1}

x^{2} = 225

- \frac{1}{2} - \frac{1}{1}
