B is the answer. It's any number that is less than 2 and -1 will become 1 because it's the absolute value.
x= 9
y= 9
4x -2y= 18.................equation 1
-4x + 2y= -18...............equation 2
From equation 1
4x= 18 + 2y
x= 18 + 2y/4
substitute 18+2y/4 for x in equation 2
-4(18+2y/4) -2y= 18
-(18+2y)-2y= 18
-18-2y-2y= 18
-18+4y= 18
4y= 18+18
4y= 36
y= 36/4
y= 9
Substitute 9 for y in equation 1
4x-2y= 18
4x-2(9)= 18
4x-18= 18
4x= 18+18
4x= 36
x= 36/4
x= 9
Hence the value of x is 9 and the value of y is 9

2/8 will simplify
Divide the top and bottom by 2
12/8 = 1/4
1/4*7
7/4
We need to change this from an improper fraction to a mixed number
4 goes into 7 once with 3 left over
