Answer:
He can buy 4 tickets
Step-by-step explanation:
you take $15.75 and divide it by $3.50 to get 4.5, then round down to get 4
4
You just have to divide the money he has by the ticket price.
The answer to that division is 4.5, but he can't buy half ticket, so the answer is 4
Let's multiply the first equation by -2 so that we can eliminate y.
-2x-4y=-20
3x+4y=8
X=-12
Since X is -12, let's plug it in to the equation to check.
-12+2y=10
2y=22; let's divide
y=11
So, D (-12,11)
