solvefor x,4x+4y=85

解答

求解

x, 4 x + 4 y = 85

x = \frac{85 - 4 y}{4}

求解步骤

4 x + 4 y = 85

将

4 y

到右边

4 x = 85 - 4 y

两边除以

4

x = \frac{85 - 4 y}{4}

9 + 3.5 g = 11 - 0.5 g 9

so l v e f or x, x y + 6 x + y = 16

so l v e f or z, lo g_{10} (x^{2} + y^{2}) z = 5 \cdot x^{2} + 5 \cdot y^{2} - 6

so l v e f or a, 10 a + b = 120

so l v e f or x, x + \frac{y}{5} = 10
