multiply both sides of equation by the denominator which is 20
then you get 5+16x=11
then move the 5 to the right side of the equation and rearrange it to get 16x=11-5, remember you always change the sign when moving numbers to the right hand side
then you get 16x=6 cuz of 11-5
then divide both sides by 16, you get x=0.375, or 3/8
