Question

Which of these simplifies to 2
3x +1 -3(x-2)+5
3x+1-2(x+2)+7
-(2x+2) +-2(x+1)
-(2x+2)+2(x+1)

Answer 1

Let's simplify each expression to see which one simplifies to 2.

1) 3x + 1 - 3(x - 2) + 5
Distribute: 3x + 1 - 3x + 6 + 5
Combine like terms: (3x - 3x) + 1 + 6 + 5
Simplify: 0x + 12
The expression does not simplify to 2.

2) 3x + 1 - 2(x + 2) + 7
Distribute: 3x + 1 - 2x - 4 + 7
Combine like terms: (3x - 2x) + 1 - 4 + 7
Simplify: x + 4
The expression does not simplify to 2.

3) -(2x + 2) + (-2)(x + 1)
Distribute: -2x - 2 - 2x - 2
Combine like terms: (-2x - 2x) + (-2 - 2)
Simplify: -4x - 4
The expression does not simplify to 2.

4) -(2x + 2) + 2(x + 1)
Distribute: -2x - 2 + 2x + 2
Combine like terms: (-2x + 2x) + (-2 + 2)
Simplify: 0x + 0
The expression simplifies to 0, not 2.

Therefore, none of these expressions simplify to 2.
