Question

Solve x + x + 2 + 2x = -2.
A) -2
B) -1
C) 0
D) 1

Answer 1

`\boxed{ \bold{ \blue{ - 1}}}`

Option B is the correct option.

Explanation:

`\mathsf{x + x + 2 + 2x = - 2}`

Collect like terms

`\mathsf{4x + 2 = - 2}`

Move constant to R.H.S and change its sign

`\mathsf{4x = - 2 - 2}`

Calculate

`\mathsf{4x = - 4}`

Divide both sides of the equation by 4

`\mathsf{ (4x)/(4) = ( - 4)/(4) }`

Calculate

`\mathsf{x = - 1}`

Hope I helped!

Best regards!

Answer 2

-2

Explanation:

Because it says it in the problem.

Since you don't know the value of x you make that a zero.

You add the x's and you get zero.

2+2x=2

= -2
