Question

determine o valor x nas proporcoes x/6 = 32/48, 1/7=x-6/49, 2x+1/10=-21/30,x-3/2x+1=4/5​

Answer 1

__________

x/6 = 32/48

48x = 32.6

48x = 192

x = 192/48

x = 4

R) x = 4

_

1/7 = x - 6/49

7x - 42 = 49

7x = 42 + 49

7x = 91

x = 91/7

x = 13

R) x = 13

_

2x + 1/10 = -21/30

60x + 30 = -210

60x = -210 - 30

60x = -240

x = -4

R) x = -4

_

x - 3/2x + 1 = 4/5

8x + 4 = 5x - 15

8x - 5x = -15 - 4

3x = -19

x = -19/3

R) x = -19/3
