Question

5•(3•x+11)•3-19+5=110

Answer 1

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 !

Answer 2

Răspuns:

$\boxed{\bf x=-\dfrac{41}{45}}$

Explicație pas cu pas:

$\bf 5\cdot (3\cdot x+11)\cdot 3-19+5=110$

$\bf 5\cdot (3\cdot x+11)\cdot 3-19=110-5$

$\bf 5\cdot (3\cdot x+11)\cdot 3=105+19$

$\bf 5\cdot (3\cdot x+11)\cdot 3=124$

$\bf 15\cdot (3\cdot x+11)=124$

$\bf 45\cdot x+ 165=124$

$\bf 45\cdot x=124-165$

$\bf 45\cdot x=-41$

$\boxed{\bf x=-\dfrac{41}{45}}$
