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)

2 david
you can also do
3+2=(5-24)=19
Answer:
61 : 60
Step-by-step explanation:
Well to make a ratio, you just have to have David time : Mark time
So if you convert Mark's time into minutes, it is 60 minutes
61 : 60
That's the simplest form.
