Question

a)x-4/10= 3/5

b)x+2/6 = x-1/2

c)3x-2/4 = x+8/2

d)x+2\3 = 15/9

e)2x/9 = x-6/5

f)5x-1/x+2 = 6/8

me ajudem a resolver essas proporções pfvvv

Answer 1

c) 2(3x-2) = 4(x+8)
6x - 4 = 4x +32
2x = 36
x = 18

d) 9(x+2) = 3.15
9x +18 = 45
9x = 27
x= 3

Answer 2

Resposta:

a) 10.3=5. (x-4)

30=5x-20

5x=30+20

5x=50

x=50/5

x=10
