Answer:
-5
Step-by-step explanation:
There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example
7x + 5y = 19
-5 (2x + y = 19) ---> -10x -5y = 95
this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!
