To do elimination, you need to get same coefficient before the variable
Multiply (-x-y = -11) by 4
-4x + 9y = -18
-4x - 4y = -44
Now subtract
13y = 26, y = 2
Plug in y = 2 for any of the two equation
-x - 2 = -11
-x = -9, x = 9
Solution: x = 9, y = 2
FRRRRRR?!?!?!?!?!?!?!?!?!
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
i'm not sure how to do the modeling and the grouping part but here's the solve and check portion. I hope i helped a little!
solve;
3x=6 divide each side by 3 to isolate x
x=2
check;
plug 2 into x and see if the statement is true.
3(2)=6
6=6 true? yes.
