Question 847648
x bottles apple juice
y bottles orange juice


{{{x+y=10}}} and {{{1.50x+2y=18}}}.  Multiply the cost equation by 2 which will give {{{3x+4y=36}}}.  Now multiply the bottle count equation by 3 to give {{{3x+3y=30}}};


You have this system set for use of the elimination method to first find y:
---------------------
3x+4y=36
----
3x+3y=30
---------------------




ANSWER:  4 bottles of apple juice and 6 bottles of orange juice
