Разложите на множители: 10ах = 13bу - 7 умножить (х-у) - 10ау-13bх

10ах=13by-7*(x-y)-10ay-13bx

13by-7(x-y)-10ay-13bx-10ax=0

13b*(y-x)-7*(x-y)-10a*(x-y)=0

-13b*(x-y)-7*(x-y)-10a*(x-y)=0

(x-y)*(-13b-7-10a)=0

(x-y)*(13b+10a+7)=0

10ax=13by-7(x-y)-10ay-13bx

13by-7(x-y)-10ay-13bx-10ax=0

13b(y-x)-7(x-y)-10a(y-x)=0

(13b-10a)(y-x)-7(x-y)=0

-(13b-10a)(x-y)-7(x-y)=0

-(x-y)(13b-10a-7)=0

(x-y)(13b-10a-7)=0
