(2+i)z+(3-2)=15-6i

解答

(2 + i) z + (3 - 2) = 15 - 6 i

解答

z = \frac{22}{5} - i \frac{26}{5}

求解步骤

(2 + i) z + (3 - 2) = 15 - 6 i

(2 + i) z + 3 - 2 = 15 - 6 i

将

3

到右边

(2 + i) z - 2 = 12 - 6 i

将

2

到右边

(2 + i) z = 14 - 6 i

两边除以

2 + i

z = \frac{22}{5} - i \frac{26}{5}

流行的例子

(2(x+2))/3 = 3/7+(5(x+1))/3

\frac{2 ( x + 2 )}{3} = \frac{3}{7} + \frac{5 ( x + 1 )}{3}

3(2-x)-(x+3)/2 =5x+x/2

3 (2 - x) - \frac{x + 3}{2} = 5 x + \frac{x}{2}

3(x+3)-3(x-3)=x

3 (x + 3) - 3 (x - 3) = x

\frac{3 x}{5} - 4 = - 6 + x
