Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
-x + 2y = 8
-x + 10y = 48
Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!
-x + 2y = 8
-x + 10y = 48
----------------subtraction eliminates x
0 - 8y = -40
y =
y = +5
:
Find x using the 1st equation, replace y with 5
-x + 2(5) = 8
-x + 10 = 8
-x = 8 - 10
-x = -2
x = +2
:
See if that check out in the 2nd equation, replace x and y
-2 + 10(5) = 48
-2 + 50 = 48; confirms our solutions
