-6(x + 1) + 4 = 16
First: eliminate parenthesis - use the distributive property.
-6(x) - 6(1) + 4 = 16
-6x - 6 + 4 = 16
-6x - 2 = 16
Sec: combine "like" terms - add 2 to both sides (when you move a term to the opposite side, always use the opposite sign).
-6x - 2+2 = 16+2
-6x = 16+2
-6x = 18
Third: divide both sides by -6.
-6x/-6 = 18/-6
x = -3

Simplifying
-6(x + 1) + 4 = 16
Reorder the terms:
-6(1 + x) + 4 = 16
(1 * -6 + x * -6) + 4 = 16
(-6 + -6x) + 4 = 16
Reorder the terms:
-6 + 4 + -6x = 16
Combine like terms: -6 + 4 = -2
-2 + -6x = 16
Solving
-2 + -6x = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + -6x = 16 + 2
Combine like terms: -2 + 2 = 0
0 + -6x = 16 + 2
-6x = 16 + 2
Combine like terms: 16 + 2 = 18
-6x = 18
Divide each side by '-6'.
x = -3
Simplifying
x = -3

- 6(x+1) + 4 = 16
- 6x - 6 + 4 = 16
- 6x -2 = 16
- 6x = 18
- x = 18/6
- x = 3

first multiply the -6 in to both x and 1.
-6(x) + -6(1) [+4] = 16
add the integers together on the left side of the equation
-6(x) + [-6(1) + 4] = 16
substract the integer on the left side of the equation fron both sides
-6(x) = 16- [-6(1)+4]
now divide by the numer on the left
(x) = (16-[-6(1)+4])/-6
there's your answer. YOU can work it out to the numbers.
Hope this helps!

1) Subtract 4 from each side
-6(x+1)=12
2) Divide both sides by -6
(x+1)= -2
3) Subtract 1 from both sides
x = -3
4) Proof
-6(-3+1) + 4 = 16
-6(-2) + 4 = 16
12 + 4 = 16
16 = 16

mutiply -6 with x and 1. you will get -6x + -6 + 4 = 16 you then add -6 plus 4. u get -2 + -6x = 16 subtract -2 from 16. now u have -6x = 16 . divide 16 by -6 and u will get -2 and 2/3

-6(x+1)+4=16
first distribute the 6 --> -6x-6+4=16
combine like terms --> -6x-2=16
+ 2 on both sides --> -6x=18
/-6 from both sides--> x=-3
FINAL ANSWER:
x=-3

-6(x+1) + 4 = 16
First, distribute -6:
-6x - 6 + 4 = 16
-6x - 2 = 16
Now bring the -2 over by adding 2 to each side:
-6x - 2 + 2 = 16 + 2
-6x = 18
Now divide both sides by -6:
-6x/-6 = 18/-6
x = -3
Hope this helps!
