expand-2(x+2=-2x+1)

expand

- 2 (x + 2 = - 2 x + 1)

- 2 x - 4 = 4 x - 2

Solution steps

- 2 (x + 2 = - 2 x + 1)

Distribute parentheses

(- 2) x + (- 2) \cdot 2 = (- 2) (- 2 x) + (- 2) \cdot 1

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

- 2 x - 2 \cdot 2 = 2 \cdot 2 x - 2 \cdot 1

Simplify

- 2 x - 2 \cdot 2 = 2 \cdot 2 x - 2 \cdot 1 : - 2 x - 4 = 4 x - 2

- 2 x - 4 = 4 x - 2
