x - 4 = 1 4 + 1 = x Therefore, x = 5
Evaluate x/y when x = 4 and y = 4. x/y = 4/4 = 1/1 = 1
One possible expression is [ 1/(x - 4)+ 1/x ].
4. 1 x 4 equals 4 - - 9 x 4 equals 36
-1/2
x equals 7
If X+Y=5;X=4, then x=4 and y=1
x = -1/4
When x = 1 then y = 4
x-1 = 4 Add 1 to both sides: x-1+1 = 4+1 x = 5
0
1/x = 4Take reciprocals of both sides: x = 1/4
