To solve this first we need to get are chunk which is already solved for here as Y=(4x) so one the chunk side of this we dont have to solve for it, so now we can just skip right to solving this equation like so. First input the numbers x+(4x)=5, Distribute/Combine like terms in this case 5x=5 Divide by 5 x=1 So now that we have x we can plug it into are chunk and then we have are answer Y=(4x) Y=(4*1) Y=4 So are end answers are Enjoy!=)
