Algebra 9th Grade Homework Help?

Nadia Crauswell: 1. For this, you must write 2 equations. In each equation, x and y will be the same thing. So for this you'd have...1st equation: x+y= 942 (x and y are the #'s of tickets sold and they amount to 942)2st equation:14x+11.75y = 12,402.75 (again, x and y are the #'s of tickets sold for each, times their prices, which amount to 12,402.75)Then you must solve the equations using either the substitution method or combination (sometimes called elimination) method. For this, let's use the substitution method.We take our two equations, and find the value of one of the variables:x+y=942-y -y______x=942-yNow, we substitute this value of x into the second equation:14(942-y) +11.75y = 12,402.75 Simplify using the distributive property:13188 - 14y + 11.75y = 12,402.75Combine the y's:13188 - 2.25y = 12,402.75 -13188 -13188____________________-2.25y = -785.25/-2.25 /-2.25y= 349Then, you substitute the value of y into the first equation:x + 349 = 942 -! 349 -349x=593So, the answer is (593, 349). (Those are the numbers of tickets.)I just did your first problem for you!Phew, lots of numbers, but it's really pretty simple, right? Hope I helped~ Will edit later!Oh my... It's already past 9 (here)! I'm afraid I can't help you with the rest. I have to do my own algebra homework! Good luck!...Show more
