(n-7)/4-(n-1)/9 =1

\frac{n - 7}{4} - \frac{n - 1}{9} = 1

n = 19

Solution steps

\frac{n - 7}{4} - \frac{n - 1}{9} = 1

Multiply by LCM

9 (n - 7) - 4 (n - 1) = 36

Expand

9 (n - 7) - 4 (n - 1) : 5 n - 59

5 n - 59 = 36

Move

59

to the right side

5 n = 95

Divide both sides by

5

n = 19

\frac{2}{3} (3 m - 6) = - 1 - m

x + 2 = 2 x + 6

3 - (0.7 + \frac{9}{12} + \frac{6}{8}) = \frac{4}{5}

2 x - 3 = 5 x + 4

x - 11 = - 8
