Question

What is the simplified expression for the expression below?

–1(2x + 3) – 2(x – 1)

–4x + 1
–4x – 2
–4x + 2
–4x – 1

Answer 1

-1(2x+3)-2(x-1)
-2x-3-2x+2
-4x-1

Answer 2

Answer:

The correct option is 4.

Step-by-step explanation:

The given expression is

$-1(2x+3)-2(x-1)$

Using distributive property we get

$-1(2x)-1(3)-2(x)-2(-1)$

On further simplification we get

$-2x-3-2x+2$

Combined like terms.

$(-2x-2x)+(-3+2)$

$(-4x)+(-1)$

$-4x-1$

The simplified form of given expression is –4x – 1.

Therefore the correct option is 4.
