Question

aflati numărul x sdiind că: 2•{12+3•[60_3•(27-4•3)}]-5x=64
va roggggggg​

Answer 1

64=2·{12+3·[60-3·(27-4·3)]}-5x=4·3=12

64=2·{12+3·[60-3·(27-12)]}-5x = 27-12=15

64=2·[12+3·(60-3·15)]-5x=3·15= 45

64=2·[12+3·(60-45)]-5x=60 - 45 =15

64=2·(12+3·15)-5x =3·15=45

64=2·(12+45)-5x = 12+45 =57

64=2·57-5x =57·2=114

64=114-64=50

x=50:5

x=10

S ={10}

Sper Că Team Ajutat!
