You can put this solution on YOUR website! 1. 7x+6y=-30
-8x+y=50
What is the solution of the system? The solution is ___? (Type an ordered pair)
Multiply the 2nd equation by 6, then subtract.
----------------
2. 6x+5y=-8
-5x+y=48
Multiply the 2nd eqn by 5 and subtract.
---------------
3. x+2=9
-x+3y=11
---------------
x = 7
-------------
4. 5x+3y=-13
7x-2y=17
What is the solution of the system? The solution is ___? (Type an ordered pair)
5. 0.3x-0.2y=4
0.2x+0.5y=-75/17
What is the solution of the system? The solution is ___? (Type an ordered pair)
6. 9x-9y=27
7y-3x=-11
Divide the 1st eqn by 3, then subtract
------------------
7. 0.05x0.25y=44
0.15x+0.05y=48
Mutliply the 2nd eqn by 5 and subtract.
---------------------
These are all similar.
----------------------
You don't need to type the following. Seeing that over and over just is just irritating, and results in your problem being ignored.
What is the solution of the system? The solution is ___? (Type an ordered pair)
