3(4-r)=0.5(6+2r)

解答

3 (4 - r) = 0.5 (6 + 2 r)

解答

r = \frac{9}{4}

+1

十进制

r = 2.25

求解步骤

3 (4 - r) = 0.5 (6 + 2 r)

在两边乘以

10

30 (4 - r) = 5 (6 + 2 r)

展开

30 (4 - r) : 120 - 30 r

展开

5 (6 + 2 r) : 30 + 10 r

120 - 30 r = 30 + 10 r

将

120

到右边

- 30 r = 10 r - 90

将

10 r

para o lado esquerdo

- 40 r = - 90

两边除以

- 40

r = \frac{9}{4}

(3.14*x)/4 =27265.91

\frac{3.14 \cdot x}{4} = 27265.91

0.15(5x-2)=0.4(x+1)

0.15 (5 x - 2) = 0.4 (x + 1)

r = (1 + i)^{16}

solvefor x,x+5y=-21

so l v e f or x, x + 5 y = - 21

1/21+1/4 (3x-1)=2 x/3-1/2

\frac{1}{21} + \frac{1}{4} (3 x - 1) = 2 \frac{x}{3} - \frac{1}{2}
