Question

TÌM X,Y BIẾT \(\frac{x-3}{y-2}=\frac{3}{2}\): X-Y=4

Answer 1

=> \(\frac{x-3}{3}=\frac{y-2}{2}\)

=> \(\frac{x-3}{3}+1=\frac{y-2}{2}+1\)

=> \(\frac{x}{3}=\frac{y}{2}=\frac{x-y}{3-2}=\frac{4}{1}=4\)

=> x = 4.3 =12

=> y = 4.2 = 8

Answer 2

\(\frac{x-3}{y-2}=\frac{3}{2}\)
=>\(\frac{x-3}{3}=\frac{y-2}{2}\)
=>\(\frac{x}{3}-1=\frac{y}{2}-1\)
=>\(\frac{x}{3}=\frac{y}{2}\)
=>2x=3y
Xét x-y  =4
=>2x-2y=8
=>3y-2y=8
=>5y=8
=>y=8/5
=>y=1,6=>x=5,6
Chẳng biết có đúng không nốt
