First you get your x's on the same side so add 1/2 to 1/5 that equals 7/10x +5=19 next you -5 from 5 and -5 from 19. So then you have 7/10x=14 then you multiply 7/10 by 7/10 so it cancels out. And you multiply 7/10 to 14. That equals 9.8 as a decimal and as a fraction it reduces down to 9 and 4/5. So x =9.8 or x= 9 4/5
