Question

lf 5×/3 ‐4=2×/5 ,then the numerical value of 2x- 7 is​

Answer 1

to find the numerical value of 2x-7 we will find the value of x in 5×/3 ‐4=2×/5

5x/3-4=2x/5

5x*2x=5*3+4

10x^2=15+4

x*x=19/10

x*x=1.9

x=1.9/2

x=0.95

the value of x is 0.55

therefore, 2*0.95-7

=1.9-7

=-5.1

i hope my answer is correct
