3a+2=3,b+4=3c+5

解答

3 a + 2 = 3, b + 4 = 3 c + 5

解答

a = \frac{1}{3}, b = 3 c + 1

求解步骤

[3 a + 2 = 3 b + 4 = 3 c + 5]

对于

3 a + 2 = 3

将

a

移到一边:

a = \frac{1}{3}

[b + 4 = 3 c + 5]

对于

b + 4 = 3 c + 5

将

b

移到一边:

b = 3 c + 1

方程组的解为:

a = \frac{1}{3}, b = 3 c + 1

流行的例子

1/x+4/y = 2/7 , 4/3 x+1/2 y=-8/5

\frac{1}{x} + \frac{4}{y} = \frac{2}{7}, \frac{4}{3} x + \frac{1}{2} y = - \frac{8}{5}

f(x)(x)^1(x)=1,+xf(x)(x)^2(x)=x^2

f (x) (x)^{1} (x) = 1, + x f (x) (x)^{2} (x) = x^{2}

x+3y=13,x^2+3y^2=43

x + 3 y = 13, x^{2} + 3 y^{2} = 43

u(y,x)-9u(y,x)=(1/2)x^4,y=6

u (y, x) - 9 u (y, x) = (\frac{1}{2}) x^{4}, y = 6

0+1/2 yy=x+150,x=15

0 + \frac{1}{2} yy = x + 150, x = 15
