0.3n=0.8+0.7n

0.3 n = 0.8 + 0.7 n

n = - 2

Solution steps

0.3 n = 0.8 + 0.7 n

Multiply both sides by

10

3 n = 8 + 7 n

Move

7 n

to the left side

- 4 n = 8

Divide both sides by

- 4

n = - 2

\frac{y}{- 5} = 2

3 x - 1 = 4 x + 8 - x

\frac{z}{- 2} = 7

- 5.5 (d - 2) = - 12.1

- \frac{x}{3} = 6
