21/12-(3x)/4 =2

\frac{21}{12} - \frac{3 x}{4} = 2

x = - \frac{1}{3}

Decimal Notation

x = - 0.33333 \dots

Solution steps

\frac{21}{12} - \frac{3 x}{4} = 2

Cancel

\frac{21}{12} : \frac{7}{4}

\frac{7}{4} - \frac{3 x}{4} = 2

Move

\frac{7}{4}

to the right side

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

Multiply both sides by

4

- 3 x = 1

Divide both sides by

- 3

x = - \frac{1}{3}

3 x - 6 = \frac{( - 9 x )}{3 + 12}

x, 5 x + 2 y + 1 = 0

15 - (7 + 3 x) = 16 - (4 x - 1)

6 (n - 3) - 2 n = 10

10 x + 9 = 7 x
