Question

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

Answer 1

Answer:

x = -6

Step-by-step 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

Answer 2

Answer:

- 6

Step-by-step 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

$\frac{3x}{3} = \frac{ - 18}{3}$

Calculate

$x = - 6$

hope this helps
