−6&gt;−30−4x<br> help please
nikklg [1K]

from both sides of the equation.

Answer:

Apply the distributive property.

6 ⋅ 5 + 6 (-3x) = -4 x - 12

Multiply

6 by 5 . 30 + 6 (-3 x) = - 4 x - 12

Multiply

− 3 by 6 . 30 - 18 x = - 4 x - 12

Add

4 x to both sides of the equation.

30 - 18 x + 4 x = - 12

Add

− 18 x and 4 x . 30 - 14 x = - 12

Subtract

30

from both sides of the equation.

- 14 x = - 12 - 30

Subtract

30 from

− 12 . - 14 x = - 42

x = 3
