You need two independent linear equations to solve for two unknown variables.
x+xy=8 xy=-x+8 y=-1+8/x
If you're solving for x, then x = 3/y.
X +13 equals 22, X equals nine
5
12 + 5 equals...
542 X 13 = 7046
5
x - 13 = 5 x = 18
If ( x = 0 ) and ( y = 1 ), then ( xy = 0 \times 1 = 0 ). Therefore, the value of ( xy ) is 0.
xy = x ÷x y = 1
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
To solve for x, we'd have to know what this expression equals.
