详细解题步骤如下:
希望能帮到你,祝学习进步!
a等于多少b,c等于多少b,然后带上b,比一下啊
根据第二个得到b等于三分之四c,根据第一个得到a等于九分之八c
a等于二分之三b,b=三分之四b,所以a比b比c等于9:6:8
由题知a:b=2:3. 所以a:b:c=8:12:9
由b:c=4:3知b不等于0
所以有a=2/3b,c=3/4b
可得a:b:c=8:12:9
已知a-b=3,a-c=4,求4a-(b-c)*(b-c)-2b-2c
3a=2b,b:c=4:3,求a:b:c 3a=2b,b:c=4:3,求a:b:c
已知:(a-b)(b-c)(c-a)/(a+b)(b+c)(c+a)=5/132,求a/(a+b)+b/(b+c)+c/(c+a)的值!(请尽快,我有急用,a/(a+b)+b/(b+c)+c/(c+a)=1/2[(a-b)/(a+b)+(b-c)/(b+c)+(c-a)/(c+a)]+3/2 (a-b)/(a+b)+(b-c)/(b+c)+(c-a)/(c+a) 没有错吧...
3a-c=4a+2b-c=a+b+c a:b:c
数学a/b=2/3 b/c=4/7 a:b:c求a:b:c=
A+C=4B B+C=3A 求A`B,C=1.1
1/a=2/b=3/c求a+b-c/a-b+c=?
15a:12b:9c=3a:2b:c,求a:b:c求出a:b:c
(a+b):(b+c):(c+a)=3:4:5 求a:b:c
已知A=3a-2b+c,B=a+4b-2c,C=a-3c,求A-(B+C).
A=3A-2B+C,B=A+4B-2C,C=A-3C,求A-(B+C)
已知a:b=3:4和b:c=5:2求a:b:c
如果a:b:c=2:3:4,求b分之a+2b-c
如果|4a-5b|+(3b-c)^2=0,求a:b:c
已知|a|=4.|b|=2.|c|=6.且|a+b|=a+b.|a+c|=-(a+c)求3a-4b+2c
已知a/(b+2c)=b/(c+2a)=c/(a+2b),且a+b+c≠0,求(3b+c)/b的值?
已知A=3A-4B+C,B=5A+4B+2C,求[1]A-B;[2]A+B;[3]2A-3B.
a:b=5:6,b:c=4:3,求b-c分之a+b
