2.2n+0.8n+5=4n

2.2 n + 0.8 n + 5 = 4 n

n = 5

Solution steps

2.2 n + 0.8 n + 5 = 4 n

Add similar elements:

2.2 n + 0.8 n = 3 n

3 n + 5 = 4 n

Move

5

to the right side

3 n = 4 n - 5

Move

4 n

to the left side

- n = - 5

Divide both sides by

- 1

n = 5

4 - 5 x = 1 + 6 x

x - 8 = - 17

\frac{1}{10} x + 1.1 = - 3.3

\frac{1}{4} (2 (x - 1) + 10) = x

- 4 x + 24 = 8 - \frac{2}{5} (10 x - 60)
