6(j-10)=-8j+10

解答

6 (j - 10) = - 8 j + 10

j = 5

求解步骤

6 (j - 10) = - 8 j + 10

展开

6 (j - 10) : 6 j - 60

6 j - 60 = - 8 j + 10

将

60

到右边

6 j = - 8 j + 70

将

8 j

para o lado esquerdo

14 j = 70

两边除以

14

j = 5

- 17 r + 6 r + 16 r + 17 r - 19 r = 12

12 + \frac{3}{2} s - \frac{1}{2} - \frac{3}{4} s = \frac{5}{4} s

\frac{1}{2} + x - \frac{x}{6} = \frac{1}{3} + 16 - \frac{2 x}{9}

so l v e f or x, x - 2 y - 4 = 0

- \frac{2}{5} h + 1 = 3 - \frac{1}{2} h + \frac{1}{2}
