докажите равенство пж помогите

Answer 1

$=\frac{c(a+b)+x(a+b)}{y(a+b)+2x(a+b)}= \frac{(a+b)(c+x)}{(a+b)(2x+y)} =\frac{c+x}{2x+y}$

Answer 2

ac+bx+ax+bc /ay+2bx+2ax+by =x+c/2x+y

(ac+ax)+(bx+bc)/(ay+2ax)+(2bx+by)=x+c/2x+y

a(c+x)+b(x+c)/a(y+2x)+b(2x+y)=x+c/2x+y

(c+x)(a+b) /(y+2x)(a+b)=x+c/2x+y

c+x/2x+y =x+c/2x+y
