Question

if 5x/2 -4 =2x/5 , then find the value of 2x-7​

Answer 1

(5x/2) - 4 = 2x/5 , then find the value of 2x - 7

First of all, we should find the value of x..

(5x/2) - 4 = 2x/5

(5x - 8)/2 = 2x/5

(5x - 8)5 = 2(2x)

25x - 40 = 4x

25x - 4x = 40

21x = 40

x = 40/21

Put the value of x in 2x-7

2×(40/21) - 7

=>( 80/21) - 7

=>(80 - 147)/21

=> -67/21
