Question 440317: i need help solving a chapter problem.
its a word problem that many students have trouble with.
So far i have gotten most of it until it said to find a number to make to solution exist.
this is what i have.
x+y=45
11x+10y= ?
i have tried 100, 80, & 81 but none of them worked , it was all no solution.
i know how to graph the problems & solve them alebraically . Its just finding a number to make it a solution is what i am having trouble with .
please help D:
if you need more info about the problem please email me.
You can put this solution on YOUR website! You can't find numbers. You now have three unknowns with only two equations.
x+y=45
y=45-x
11x+10y= ?
11x+10*(45-x)=
11x+450-10x=x+450
11x+10y=x+450
10x+10y=450
x+y=45
You can only solve in terms of x or in terms of y.
