Please show me how they figured this out? > I am knew at word problems..grade 10. > ************************************************************************ Let x=Craig's age and y=Collin's age Then x=2y-1 and 45=3x+2y Thus 3(2y-1)+2y=6y-3+2y=8y-3=45 You can see that y must be equal to 6 and: x=2(6)-1=11 You have your answer...
