7-9x=10

解答

7 - 9 x = 10

x = - \frac{1}{3}

十进制

x = - 0.33333 \dots

求解步骤

7 - 9 x = 10

将

7

到右边

- 9 x = 3

两边除以

- 9

x = - \frac{1}{3}

so l v e f or x, x + 5 y = 3

so l v e f or x, I n (x) - 2 I n (3) = 1

so l v e f or x, y - 1 = 4 (x + 2)

so l v e f or z, w \cdot (- 4 + z) = m z + 17

so l v e f or x, 4 y - 6 x = 12
