Question

if x={3/5-(2/7-1/4)} solve it​

Answer 1

Answer:

x= {3/5-(2/7-1/4)}

= {3/5-(8-7/28)}

=(3/5-1/28)

=(84-5/140)

=79/140 or_ 5.06 (ans.)

Answer 2

Answer:

x = 79/140 or 0.56.

Step-by-step explanation:

x = [3/5 - (2/7 - 1/4)]

x = [3/5 - (8-7)/28]

x = 3/5 - 1/28

x = (84 - 5)/28

x = 79/140

∴ x = 0.56.
