x=53

d)

5x+10=65

5x=55

x=11

e)

4x+24=8

4x=-16

x=-4 .(-1)

x=4

f)

9x+10=89

9x=79

x=79/9

g)

11x=101

x=101/11

Answer 2

Explicação passo-a-passo:

a) x-9 = 10

x = 10 + 9

x = 19

b) x + 13 = 11

x = 11 - 13

x = - 2

c) x + 7 = 60

x = 60 - 7

x = 53

d) 5x + 10 = 65

5x = 65 - 10

5x = 55

x = 55/5

x = 11

e) 4x + 24 = 8

4x = 8 - 24

4x = - 16

x = - 16/4

x = - 4

f) 9x + 10 = 89

9x = 89 - 10

9x = 79

x = 79/9

x = 8,77...

g) 8x + 60 = 100

8x = 100 - 60

8x = 40

x = 40/8

x = 5

h) 11x - 10 = 111

11x = 111 +10

11x = 121

x = 121/11

x = 11
