Question

Calcule o valor de x nas proporções:
a) 2+x/4 = x/3
b) x-1/4 = x/6
c) x-1/6 = 9/12
d) 5-x/x+1 =6/2

Answer 1

A) 2 + X/4 = X/3

8 + X = 4X + 12

X - 4X = 12 - 8

-3X = 4

X = -4/3

B) X - 1/4 = X/6

12X - 3 = 2X

12X - 2X = 3

10X = 3

X = 3/10

C) X - 1/6 = 9/12

X - 1/6 = 3/4

X = 3/4 + 1/6

X = 11/12

D) 5 - X/X+1 = 6/2

X - X/X + 1 = 6/2

X - 1 + 1 = 3

X = 3
