Answer 1

Answer:

3(7x-1)=1/4

7x-1=3/4

7x=3/4 +1

7x=7/4

x=7/4 x 7

x=1/4

Answer 2

(1/3)(7x-1) = 1/4

Equating RHS to 0 by taking 1/4 on LHS, we get

(1/3) X (7x-1)-(1/4) = 0

(1/3) X (7x-1)-1/4 = 0

1/3 X (7x-1)-1/4 = 0

(1/3) X 4 X (7x-1))/4-1/4 = 0

(1/3) X 4 X (7x-1)-1 = 0

28/3 X x-7/3 = 0

(28/3 X x-7/3)/4 = 0

(28/3 X x-7/3)/4 = 0 X 4

28/3 X x-7/3 = 0

28/3 X x-7/3 = 0 + 7/3

28/3 X x = 7/3 / 28/3

x = 7/3/28/3

x = 1/4

Hence, x=1/4
