Đáp án:
Giải thích các bước giải:
` x/5 - 1/2 = 6/(y+2) `
`(2x-5)/10=6/(y+2)`
`(2x-5).(y+2)=6.10=60=1.60=2.30=30.2=4.15=5.12`
` =6.10=(-1).(-60)=(-2).(-30)=(-30).(-2)=(-4).(-15)=(-5).(-12) = (-6).(-10) `
\begin{array}{|c|c|}\hline 2x-5&1&3&15&5&(-1)&-3&-15&-5\\\hline x&3&4&10&5&2&1&-5&0\\\hline\end{array}
\begin{array}{|c|c|}\hline y+2&60&20&4&12&-60&-20&-4&-12\\\hline y&58&18&2&10&-62&-22&-6&-14\\\hline\end{array}
Vaayj`(x;y)=(3;58);(4;18);(10;2);(5;10);(2;-62);(1;-22);(-5;-6);(0;-14)`
