2/5 n+1/10 = 1/2 (n+4)

\frac{2}{5} n + \frac{1}{10} = \frac{1}{2} (n + 4)

n = - 19

Solution steps

\frac{2}{5} n + \frac{1}{10} = \frac{1}{2} (n + 4)

Expand

\frac{1}{2} (n + 4) : \frac{1}{2} n + 2

\frac{2}{5} n + \frac{1}{10} = \frac{1}{2} n + 2

Move

\frac{1}{10}

to the right side

\frac{2}{5} n = \frac{19}{10} + \frac{1}{2} n

Move

\frac{1}{2} n

to the left side

- \frac{1}{10} n = \frac{19}{10}

Multiply both sides by

- 10

n = - 19

0 = 3 x - 9

4 = \frac{t}{- 7}

\frac{4 x - 1}{3} = \frac{12 x - 3}{7}

4 x - 6 = 16

x + \frac{4}{5} = 8 \frac{9}{10}
