8x-12=15x-4x

8 x - 12 = 15 x - 4 x

x = - 4

Solution steps

8 x - 12 = 15 x - 4 x

Add similar elements:

15 x - 4 x = 11 x

8 x - 12 = 11 x

Move

12

to the right side

8 x = 11 x + 12

Move

11 x

to the left side

- 3 x = 12

Divide both sides by

- 3

x = - 4

\frac{3 x + 14}{4} - 16 = - 15

∣ x - 9 ∣ = 2

4 x^{2} + 6 x - 4 = 0

- 4 r^{2} + 1

6 x^{2} - 7 x - 4 = 0
