Răspuns: [tex]\green{\bf~ x = 36~}[/tex]
Explicație pas cu pas:
[tex]\bf 9\cdot\big(x-3\big)=7\cdot\big (x+5\big)+10[/tex]
[tex]\bf 9x-27=7x+35+10[/tex]
[tex]\bf 9x=7x+35+10+27[/tex]
[tex]\bf 9x=7x+72[/tex]
[tex]\bf 9x-7x=72[/tex]
[tex]\bf 2x=72~~~\bigg|:2[/tex]
[tex]\red{\boxed{\bf~ x = 36~}}[/tex]
