solvefor h, 2/3 h-1/3 h+11=8

解答

求解

h, \frac{2}{3} h - \frac{1}{3} h + 11 = 8

h = - 9

求解步骤

\frac{2}{3} h - \frac{1}{3} h + 11 = 8

将

11

到右边

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

在两边乘以

3

h = - 9

(x^{2} + 3 x - 7) - (3 x^{2} - 5 x + 3)

x, \frac{3}{4} = \frac{6}{x}

∣ - 19 ∣

x^{2} - 3 x = 4 x

n, n \cdot 0.11 (n - 1) + 35 = 3 n
