16-1/2 x= 3/4 x+1

解答

16 - \frac{1}{2} x = \frac{3}{4} x + 1

x = 12

求解步骤

16 - \frac{1}{2} x = \frac{3}{4} x + 1

将

16

到右边

- \frac{1}{2} x = \frac{3}{4} x - 15

将

\frac{3}{4} x

para o lado esquerdo

- \frac{5}{4} x = - 15

在两边乘以

4

- 5 x = - 60

两边除以

- 5

x = 12

so l v e f or y, 6 x + 2 y = 10

so l v e f or x, 3 (x + 2) = 2 y

8 - 2 x = 12 + 4 x

4 (x - 3) + 12 = 15 - 5 (x + 6)

- \frac{3}{4} - \frac{1}{2} x = - \frac{7}{8} - \frac{5}{6} x
