Question

Calcule o valor de x. X 12,5 7,5

Answer 1

Resposta:

7/5=x/10

5x = 70

x = 70/5

x = 14

5x/2=1/2

10x = 2

x = 2/10

x = 1/5

6/x=12/5

12x = 30

x = 30/12

x = 15/6

x+7/8=5/4

4x + 28 = 40

4x = 12

x = 12/4

x = 3

2/3x=5/30

15x = 60

x = 60/15

x = 4

x-2/5= 2+x/7

7x - 14 = 10 + 5x

7x - 5x = 10 + 14

2x = 24

x = 24/2

x = 12
