Multiplying
color(blue)"All" terms on both sides of the equation by 12 will eliminate the fractions.
cancel(12)^4xxx/cancel(3)^1+cancel(12)^3xxx/cancel(4)^1=(1xx12) which simplifies to.
4x+3x=12rArr7x=12 To solve for x divide both sides by 7.
(cancel(7) x)/cancel(7)=12/7
rArrx=12/7" is the solution"
