5/2x" may be written" (5x)/2 That is
(5x)/2=10 multiply both sides of the equation by 2 to eliminate the fraction.
color(red)(cancel(2)color(black)(xx(5x)/cancel(2)=color(red)2 xx10 we are now left with 5x = 20
divide both sides by 5 to solve for x
(cancel(5)^1 x)/cancel(5)^1=cancel(20)^4/cancel(5)^1rArrx=4" is the solution" check:
(5x)/2=(5xx4)/2=20/2=10" true"
