Question

2(x+1)=-6

Answer 1

I thought you were able to work these out already. Still don't get them? Start by expanding 2(x+1), multiply (x+1) by 2.

Answer 2

Simplifying
2(x + 1) = -6
Reorder the terms:
2(1 + x) = -6
(1 * 2 + x * 2) = -6
(2 + 2x) = -6
Solving
2 + 2x = -6
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 + 2x = -6 + -2
Combine like terms: 2 + -2 = 0
0 + 2x = -6 + -2
2x = -6 + -2
Combine like terms: -6 + -2 = -8
2x = -8
Divide each side by '2'.
x = -4
Simplifying
x = -4
