(x-1)+2(3x+2)=10

解答

(x - 1) + 2 (3 x + 2) = 10

x = 1

求解步骤

(x - 1) + 2 (3 x + 2) = 10

x - 1 + 2 (3 x + 2) = 10

将

1

到右边

x + 2 (3 x + 2) = 11

乘开

2 (3 x + 2) : 6 x + 4

x + 6 x + 4 = 11

2 x - (6 x + 2) = 2 (x - 10)

x - 2 x = 7

\frac{7}{4} x - \frac{1}{3} = \frac{3}{2} x - \frac{1}{3}

P = 3 \cdot 600 \cdot 4.212422197 \cdot 1 0^{- 4}

x + 18 = 20
