-2(18-3y)=7y+2y

- 2 (18 - 3 y) = 7 y + 2 y

y = - 12

Solution steps

- 2 (18 - 3 y) = 7 y + 2 y

Add similar elements:

7 y + 2 y = 9 y

- 2 (18 - 3 y) = 9 y

Expand

- 2 (18 - 3 y) : - 36 + 6 y

- 36 + 6 y = 9 y

Move

36

to the right side

6 y = 9 y + 36

Move

9 y

to the left side

- 3 y = 36

Divide both sides by

- 3

y = - 12

5 x^{2} + 4 x + 1 = 0

r^{2} - 1

5 x - 3 \leq 2 x

- \frac{1}{3} (4 a - 5) + \frac{1}{4} (5 a - 4) \geq 0

∣ 8 x - 5 ∣ + 5 = 9
