To solve these problems you need to use the quadratic formula which is listed below.

So, if you take #2.
The

has a 1 in front of it. The x has a -3 in front of it. The last number is also -3. So:
a = 1
b = -3
c = -3
Then you can plug all of these into the equation and simplify. Which gives you:
y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5
