Explicație pas cu pas:
3x-3+2y+4=24=>3x+2y+1=24=>3x+2y=23| *2=> 6x+4y=46
3y+3+[tex]x^{2}[/tex]=[tex]x^{2}[/tex]-1-2x=> [tex]x^{2} -x^{2}[/tex]+2x+3y=-1-3=>2x+3y=-4|*(-3)=> -6x-9y=12
----------------(+)=>
-5y=66=> y=-[tex]\frac{66}{5}[/tex]
2x+3*-[tex]\frac{66}{5}[/tex]=-4 => 2x=-4+[tex]\frac{198}{5}[/tex]=>2x=[tex]\frac{-20}{5}+\frac{198}{5}[/tex]=> 2x=[tex]\frac{178}{5}[/tex]=> x=[tex]\frac{89}{5}[/tex]
