Solve this system algerbraically.
2x+ 6y = 17
2x -10y= 9
---------------
I don't know how to do it algerbraically.
Or algebraically.
-----------------
2x+ 6y = 17
2x -10y= 9
----------- Subtract
16y = 8
y = 1/2
-----------
2x -10y= 9
2x - 5 = 9
2x = 14
x = 7

Step 1 is to subtract an . This is algebra, not algerbra.





Multiply the 2nd equation by -1:





Add the like terms in the two equations:



Hence,





Substitute this value back into either of the original equations:







Therefore the solution set is
