b = - \frac{5}{12}

Decimal Notation

b = - 0.41666 \dots

Solution steps

\frac{3}{8} - \frac{3}{10} b = \frac{1}{2}

Move

\frac{3}{8}

to the right side

- \frac{3}{10} b = \frac{1}{8}

Multiply both sides by

10

- 3 b = \frac{5}{4}

Divide both sides by

- 3

b = - \frac{5}{12}

a, f = 2 (a + b) + 5

12 x + 2 [6 + 7 (x + 1)] = 0

\frac{2 x - 3}{5} - \frac{4 - 7 x}{3} - \frac{7}{30} = \frac{5 x - 9}{6}

y, 2 x + 7 y = 14

a, 2 a + b = 1
