Question

3(x+4)-1=-7 plz help

Answer 1

- 6

Explanation:

`3(x + 4) - 1 = - 7`

Distribute 3 through the parentheses

`3x + 12 - 1 = - 7`

Calculate the difference

`3x + 11 = - 7`

Move constant to R.H.S and change it's sign

`3x = - 7 - 11`

Calculate

`3x = - 18`

Divide both sides of the equation by 3

`(3x)/(3) = ( - 18)/(3)`

Calculate

`x = - 6`

hope this helps

Best regards!!

Answer 2

x = -6

Explanation:

3(x+4)-1=-7

Add 1 to each side

3(x+4)-1+1=-7+1

3(x+4)=-6

Divide by 3

3/3(x+4)=-6/3

x+4 = -2

Subtract 4 from each side

x+4-4 = -2-4

x = -6
