0.3n=2.1(n-4),15=4

0.3 n = 2.1 (n - 4), 15 = 4

n = \frac{14}{3}

Decimal Notation

n = 4.66666 \dots

Solution steps

0.3 n = 2.1 (n - 4)

Multiply both sides by

10

3 n = 21 (n - 4)

Expand

21 (n - 4) : 21 n - 84

3 n = 21 n - 84

Move

21 n

to the left side

- 18 n = - 84

Divide both sides by

- 18

n = \frac{14}{3}

120 - (x + 96) = 24

13 - (5 x + 11) = 6 x

B, a B = d

23 x - 13 = 11 + 13 x

y, 4 x + 5 y + 3 = 0
