Răspuns:
x = - 41/45
Explicație pas cu pas:
Salut !
5•(3•x + 11)•3 - 19 + 5 = 110
(15x + 55)·3 = 110 + 19 - 5
45x + 165 = 124
45x = 124 - 165
45x = - 41
x = - 41/45
Bafta !

Explicație pas cu pas:
[tex]\bf 5\cdot (3\cdot x+11)\cdot 3-19+5=110[/tex]
[tex]\bf 5\cdot (3\cdot x+11)\cdot 3-19=110-5[/tex]
[tex]\bf 5\cdot (3\cdot x+11)\cdot 3=105+19[/tex]
[tex]\bf 5\cdot (3\cdot x+11)\cdot 3=124[/tex]
[tex]\bf 15\cdot (3\cdot x+11)=124[/tex]
[tex]\bf 45\cdot x+ 165=124[/tex]
[tex]\bf 45\cdot x=124-165[/tex]
[tex]\bf 45\cdot x=-41[/tex]
[tex]\boxed{\bf x=-\dfrac{41}{45}}[/tex]
