himpunan penyesaian dr sistem prsamaan x-y=5 dan x²-y²=45 adlh

[tex]$\displaystyle{\begin{split} x-y & = 5 \\ x & = y+5 \end{split}}[/tex]


[tex]$\displaystyle{\begin{split} x^2-y^2 & = 45 \\ (y+5)^2-y^2 & = 45\\ y^2+10y+25-y^2 &= 45\\ 10y&=20\\ y&=2 \end{split}}[/tex]


[tex]$\displaystyle{\begin{split} x & = y+5 \\ & = 2+5\\ &= 7 \end{split}}[/tex]
