Question

If 10/6-8=4x/10, then the numerical value of 2x-7 is ?

Answer 1

As 10/6-8=4x/10

then

10/6-8×6/1×6=4x/10

=10/6-48/6=4x/10

=-38/6=4x/10

=-38/6×10=4x

=-190/3=4x

=-190/3×1/4=×

=-190/12=x

=-95/6=x

then put the value of x in equation

2x-7

=2×-95/6-7

=-95/3-7

=-95/3-7×3/1×3

=-95/3-21/3

=-116/3
