Answer:
x=2
y=−1
Step-by-step explanation:
You can multiply the second equation by 3:
{2x-3y=7
{9x+3y=15 add the two together (in columns):
11x+0=22
so that x=22/11=2
substitute this back into the first equation:
2*2-3y=7
y=-1
Answer:
that's an interesting channel name...
Step-by-step explanation:
Lets say y is number of adult tickets and x is number of student tickets
x+y=348
2x+y=348
(2x since I know that the student tickets are twice as much as adult tickets)
I now know that that student tickets make up 2/3 of the total number of tickets and 1/3 make up the number of adults tickets. So...
1/3 x 348= 116 adult tickets
2/3 x 348=232 student tickets
