Solve for x: 3 (x + 1) = - 2 (x - 1) - 4.

1

-1

-5

-25

3x + 3 = - 2x + 2 - 4

3x + 3 = - 2x - 2

Add 2 to each side

3x + 5 = - 2x

Subtract - 3x from both sides

5 = - 5x

Divide each side by 5

1 = - x

Since you can leave x negative you reverse it with 1 and your answer will be >>> x = - 1

-1 is the answer.

(Distribute 3 through the parenthesis and then distribute-2 through the parenthesis)

3x+3 = + 2x+2-4

(Move the variable to the left side and change its sign and then move the constant to the right side and change its sign)

3x+2x = - 2-3

(Collect the like and then calculate the sum or difference)

5x = - 1

(Divide both sides of the equation by 5)

x = - 1
