3 + (x × 4) - 15 = 1

3 + (x × 4) = 1 + 15

3 + (x × 4) = 16

(x × 4) = 16 - 3

(x × 4) = 13

x = 13 : 4

Đặt \(\frac{a}{b}=\frac{c}{d}=k\Rightarrow a=bk;c=dk\)

Khi đó \(\frac{a-b}{a+b}=\frac{bk-b}{bk+b}=\frac{b\left(k-1\right)}{b\left(k+1\right)}=\frac{k-1}{k+1}\)   (1)

\(\frac{c-d}{c+d}=\frac{dk-d}{dk+d}=\frac{d\left(k-1\right)}{d\left(k+1\right)}=\frac{k-1}{k+1}\)   (2)

Từ (1) và (2) \(\Rightarrow\frac{a-b}{a+b}=\frac{c-d}{c+d}\)   (đpcm)
