15a=3,b=5c

解答

15 a = 3, b = 5 c

解答

a = \frac{1}{5}, b = 5 c

求解步骤

[15 a = 3 b = 5 c]

[15 a = 3]

对于

15 a = 3

将

a

移到一边:

a = \frac{1}{5}

用

c

来表示

b

b = 5 c

方程组的解为:

a = \frac{1}{5}, b = 5 c

流行的例子

u^{53} n = 3 u, m = 5

2a^2=3,b+82b^2=3a+8a^2+b^2

2 a^{2} = 3, b + 82 b^{2} = 3 a + 8 a^{2} + b^{2}

1x^2+7x+12=0,11*2y^2+17y+35=0

1 x^{2} + 7 x + 12 = 0, 11 \cdot 2 y^{2} + 17 y + 35 = 0

7x-2 y/x y=5,8x+7 y/x y=15

7 x - 2 \frac{y}{x} y = 5, 8 x + 7 \frac{y}{x} y = 15

3 x + y = 1, 3 x + y = 17
