0.3d-(1/31)/3 =((0.84)/7)/(15)

0.3 d - \frac{\frac{1}{31}}{3} = \frac{\frac{0.84}{7}}{15}

d = \frac{436}{6975}

Decimal Notation

d = 0.06250 \dots

Solution steps

0.3 d - \frac{\frac{1}{31}}{3} = \frac{\frac{0.84}{7}}{15}

\frac{\frac{1}{31}}{3} = \frac{1}{93}

0.3 d - \frac{1}{93} = \frac{\frac{0.84}{7}}{15}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

0.3 d - \frac{1}{93} = \frac{0.84}{7 \cdot 15}

Multiply the numbers:

7 \cdot 15 = 105

0.3 d - \frac{1}{93} = \frac{0.84}{105}

Multiply both sides by

100

30 d - \frac{100}{93} = \frac{4}{5}

Move

\frac{100}{93}

to the right side

30 d = \frac{872}{465}

Divide both sides by

30

d = \frac{436}{6975}

x, e x - 2 y = 3 z

10 x + 8 - 2 x = 8 x + 18

x, 21 - 6 y = 27 - 8 x

10 x + 13 (x - 28500) = 860000

- 8 x - 4 = 3 x + 5
