Question

3(4x + 1) – 4x + 3 = -18

Answer 1

x= -3

Explanation:

SOOOOO, we're going to distribute, okay?

3(4x+1) = 12x+3

so now

12x+3-4x+3= -18

SO now we combine like terms, okay?

8x+6= -18

-6 -6

8x= -24

x= -3

Answer 2

`x=-3`

Explanation:

`3(4x + 1) - 4x + 3 = -18`

Subtract 3 from both sides:

`3\left(4x+1\right)-4x+3-3=-18-3`

`3\left(4x+1\right)-4x=-21`

Expand:

`3*4x+3* 1-4x=-21`

`12x+3-4x=-21`

`8x+3=-21`

Subtract 3 from both sides:

`8x+3-3=-21-3`

`8x=-24`

Divide both sides by 8:

`(8x)/(8)=(-24)/(8)`

`x=-3`
