Question

1) Resolva as equações? a) X + 3 = 5 b) Y – 10 = 12 c) 2X + 4 = 32 d) 10Y – 12 = 40 e) 2/5 X – 14 = 60​

Answer 1

Resposta:

a)x+3=5

x=5 -3

x= 2

b)y-10=12

y=12+10

y= 22

c)2x+4=32

2x=32-4

2x= 28

x=28/2

x= 14

d)10y-12=40

10y= 40+12

10y= 52

y=52/10

y= 5.2

a é não sabo

Answer 2

Resposta:

1)

a) x= 2, 2+3=5

b) y= 22, 22-10=12

c) x= 14, 2x14=28, 28+4=32

d) y= 5,2, 10x5,2= 52, 52-10=40

e) x= 185, 2/5x185=74, 74-14= 60
