1 1/2-x= 1/10

1 \frac{1}{2} - x = \frac{1}{10}

x = 1 \frac{2}{5}

Decimal Notation

x = 1.4

Solution steps

1 \frac{1}{2} - x = \frac{1}{10}

Convert mixed numbers to improper fractions:

1 \frac{1}{2} = \frac{3}{2}

\frac{3}{2} - x = \frac{1}{10}

Move

\frac{3}{2}

to the right side

- x = - \frac{7}{5}

Divide both sides by

- 1

x = \frac{7}{5}

Convert improper fractions to mixed numbers:

\frac{7}{5} = 1 \frac{2}{5}

x = 1 \frac{2}{5}

\frac{x - 1}{2} = \frac{x - 3}{4} - \frac{x - 4}{5}

30 = \frac{1}{2} (x - 50)

4 (3 x - 2) = 2 [x - 5 (x - 6)]

2 \frac{1}{2} x - 1 \frac{5}{8} = 2 \frac{3}{4}

x, k x + 12 = 3 k x
