9f= 1/2 (12f-2)

9 f = \frac{1}{2} (12 f - 2)

f = - \frac{1}{3}

Decimal Notation

f = - 0.33333 \dots

Solution steps

9 f = \frac{1}{2} (12 f - 2)

Expand

\frac{1}{2} (12 f - 2) : 6 f - 1

9 f = 6 f - 1

Move

6 f

to the left side

3 f = - 1

Divide both sides by

3

f = - \frac{1}{3}

3 x + 2 < - 5

6 - y = \frac{( y - 3 ) ^{2}}{4}

e^{2} + e^{- 2}

200 x^{2} - 50

5 x - 1 = 12 x - 57
