3 x + 5 (x - 1) = 12

x = \frac{17}{8}

Decimal Notation

x = 2.125

Solution steps

3 x + 5 (x - 1) = 12

Expand

5 (x - 1) : 5 x - 5

3 x + 5 x - 5 = 12

Add similar elements:

3 x + 5 x = 8 x

8 x - 5 = 12

Move

5

to the right side

8 x = 17

Divide both sides by

x = \frac{17}{8}

5 = c + 8 c - 4

0.03 = 1288 \cdot 0.15 \cdot 0.04 \cdot x

13 x = 13

4 (4 + 3 k) = 52
