Question 714560: How do you solve this with elimination?
3x + 5y = -48
4x - 10y = -24

3x+%2B+5y+=+-48
4x+-+10y+=+-24
Divide both sides of the lower equation by 2, so the factor of y becomes opposite to the factor of y in the upper equation.
%284x+-+10y%29%2F2+=+%28-24%29%2F2
2x+-+5y+=+-12
Since they are now the opposite of each other they disappear when you add them.
Examples:
+-2y+%2B+2y+=+0
+123y+-+123y+=+0
So when you add the equations together you get this:
3x+%2B+2x+%2B+5y+-+5y+=+-48+-+12
5x+=+-60
x+=+-30
