-7x+4(-5x+12)=-141

- 7 x + 4 (- 5 x + 12) = - 141

x = 7

Solution steps

- 7 x + 4 (- 5 x + 12) = - 141

Expand

4 (- 5 x + 12) : - 20 x + 48

- 7 x - 20 x + 48 = - 141

Add similar elements:

- 7 x - 20 x = - 27 x

- 27 x + 48 = - 141

Move

48

to the right side

- 27 x = - 189

Divide both sides by

- 27

x = 7

x^{2} - 2 x - 120 = 0

y - 7 = 0

16 x^{2} + 9 = 0

p - 4 < 1

3 ∣ x - 4 ∣ - 1 < 17
