8-7/10 c=6-1/5 c

解答

8 - \frac{7}{10} c = 6 - \frac{1}{5} c

c = 4

求解步骤

8 - \frac{7}{10} c = 6 - \frac{1}{5} c

将

8

到右边

- \frac{7}{10} c = - \frac{1}{5} c - 2

将

\frac{1}{5} c

para o lado esquerdo

- \frac{1}{2} c = - 2

在两边乘以

- 2

c = 4

- 6 = 1 + \frac{n}{- 4}

so l v e f or y, 3 x + y = 14

so l v e f or y, 3 x + 2 y = 9

so l v e f or y, 4 x - 3 y = 24

4 y - 6 = 10
