-2=0.89((x-1)/(0.447))+0.89x

解答

- 2 = 0.89 (\frac{x - 1}{0.447}) + 0.89 x

解答

x = - 0.00310 \dots

求解步骤

- 2 = 0.89 (\frac{x - 1}{0.447}) + 0.89 x

交换两边

0.89 (\frac{x - 1}{0.447}) + 0.89 x = - 2

展开

0.89 (\frac{x - 1}{0.447}) + 0.89 x : 2.88105 \dots x - 1.99105 \dots

2.88105 \dots x - 1.99105 \dots = - 2

将

1.99105 \dots

到右边

2.88105 \dots x = - 0.00894 \dots

两边除以

2.88105 \dots

x = - 0.00310 \dots

solvefor x,6x-3y=10

so l v e f or x, 6 x - 3 y = 10

k*(100(20+200))/((2+2)((50)^2+7500))=5

k \cdot \frac{100 ( 20 + 200 )}{( 2 + 2 ) ( ( 50 ) ^{2} + 7500 )} = 5

x + 2 = 0

(1050)+(2y)=1504

(1050) + (2 y) = 1504
