-2x + 9y = 56
9x – 9y = 0
Add these two equations
7x + 0y = 56
7x = 56
x = 8
Substitute x = 8 in either equation to find y.
Then check your solution for x and y in the original equation(s).
. Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
-2x + 9y = 56
9x – 9y = 0

Determine whether the point (0, 8) is a solution of the system
-3x + 9y = 72 / 9x + 3y = 24
-3x + 9y = 72 / 9x + 3y = 24
