展开 x-(2x+1=8-(3x+3))

解答

展开

x - (2 x + 1 = 8 - (3 x + 3))

- x - 1 = 3 x + 11

求解步骤

x - (2 x + 1 = 8 - (3 x + 3))

= x - (2 x + 1 \cdot 8 = - (3 x + 3))

- (2 x + 1 = 8 - (3 x + 3)) : - 2 x - 1 = 8 + (3 x + 3)

x - 2 x - 1 = 8 + (3 x + 3)

化简

x - 2 x - 1 = 8 + (3 x + 3) : - x - 1 = 3 x + 11

- x - 1 = 3 x + 11
