Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this. 14x + 18y = -54,-4x – 14y = 42

1 answer

14x + 18y = -54
-4x – 14y = 42

multiply top by 2, bottom by 7, and add:

28x + 36y = -108
-28x - 98y = 294

-62y = 186
y = -3
so, x = 0
