The ordered pair is only a solution to the first equation, so it is not a solution to the system.
2 x 10 = 20 5 x 5 = 25 20 - 25 = -5 True!
10 + 2 x 5 = 11? False! 10 + 2 x 5 = 20
So, A and C are the correct answers!
2/5 because if you subtract 5/5 of 3/5 it will give you 2/5
y - x = 1.
or, y= 1+x
y - 2x = 3.
=>1+x -2x= 3 (substituting the value of y)
=>-x= 2
=>x= -2
y = -2+1 = -1
Therefore, x = -2 and y = -1
