21 x - 6 x = 27 - 8 x

x = \frac{27}{23}

Decimal Notation

x = 1.17391 \dots

Solution steps

21 x - 6 x = 27 - 8 x

Add similar elements:

21 x - 6 x = 15 x

15 x = 27 - 8 x

Move

8 x

to the left side

23 x = 27

Divide both sides by

x = \frac{27}{23}

3 x = 6 x - 15, x + 8

12 x + 12 = 72

3 (- 2 R - 5) + 4 = \frac{R}{2} + 2

x, 2 x + 3 y = 1500

x, y - x = - 6
