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

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.
