Answer:
-5x
Step-by-step explanation:
Remember, if you multiply a negative number by a negative number, you will get a positive number, and positive numbers are greater than negative numbers. In this case, if I were to multiply each of these expressions with -1, I would get the following:
7(-1)+4=-3
-1-4=-5
5(-1)=-5
-5(-1)=5
And I'm sure you can imply how these values will correspond to other negative values. Basically, the last expression gives us a positive answer, which is larger than the others (which give a negative answer).
2 x - y = 2
- x + 5 y = 3 / *2
----------------------
2 x - y = 2
+
- 2 x + 10 y = 6
-----------------------
9 y = 8, y = 8/9
2 x - 8/9 = 2
2 x = 2 + 8 /9
2 x = 26/9
x = 13/9
( x, y ) = ( 13/9, 8/9 )
