Question

Determine o valor de X
A) x+10=35
B)-5+x=10
C)-15+x-5=52
D)3x-15=40
E)20-10x=100

Answer 1

Olá...

a)

x + 10 = 35

x =35 - 10

x = 25

b)

- 5 + x = 10

x = 10 + 5

x = 15

c)

- 15 + x - 5 = 52

x = 52 + 5 + 15

x = 72

d)

3x - 15 = 40

3x = 40 + 15

3x = 55

x = 55/3

e)

20 - 10x = 100

- 10x = 100 - 20

- 10x = 80 (- 1)

10x = - 80

x = - 80/10

x = - 8
