Question

me ajuda por favor ​

Answer 1

Resposta:

a) x=6

b) x=61/60 ou 1,016

c) x=-27/2 ou -13,5

d) x=5

Explicação passo-a-passo:

a) x/3+5= -4+11

x/3+5= 7

x/3=7-5

x/3=2

x=2•3

x=6

b) 2x -1/3=1/5+3/2

2x -1/3=2/10+15/10

2x -1/3=17/10

2x=17/10+1/3

2x=51/30+10/30

2x=61/30

X=61/30÷2

X=61/30•1/2

X=61/60

c) 2x/3+5=7-11

2x/3+5= -4

2x/3= -4-5

2x/3= -9

2x= -9•3

2x= -27

x= -27/2

d) 2x/5+1/3=x/5+2/3

2x/5-x/5=2/3+1/3

x/5=3/3

x/5=1

x=1•5

x=5
