Question 461159: Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
-3x – 8y = -88
-3x – 2y = -40

You can put this solution on YOUR website!
-3 x -8 y = -88 .............1
-3 x -2 y = -40 .............2

multiply (1)by 1
Multiply (2) by -4
-3 x -8 y = -88
12 x +8 y = 160
Add the two equations
9 x = 72
/ 9
x = 8
plug value of x in (1)
-3 x -8 y = -88
-24 -8 y = -88
-8 y = -88 + 24
-8 y = -64
y = 8
