1/3 (9y+3)+1/3 (6y-9)<13

\frac{1}{3} (9 y + 3) + \frac{1}{3} (6 y - 9) < 13

y < 3

Interval Notation

(- \infty, 3)

Solution steps

\frac{1}{3} (9 y + 3) + \frac{1}{3} (6 y - 9) < 13

\frac{1}{3} (9 y + 3) = \frac{9 y + 3}{3}

\frac{1}{3} (6 y - 9) = \frac{6 y - 9}{3}

\frac{9 y + 3}{3} + \frac{6 y - 9}{3} < 13

Multiply both sides by

3

15 y - 6 < 39

Move

6

to the right side

15 y < 45

Divide both sides by

15

y < 3

10 x^{2} - 3 x - 4 = 0

x^{2} e^{x} - 2 e^{x} < 0

\frac{p}{2} - 22 \leq - 21

2 x + 5 < 17

\frac{- 23 + 11 i}{5 + i}
