To find y in the equation x + y = 4 given that x = 32/4, first simplify x = 32/4 to x = 8. Then substitute 8 for x in the equation as shown: (8) + y = 4. To solve for y, subtract 8 from both sides of the equation, and the result is y = -4
If x is 32/4 then what is y in condition x+y=4?

First evaluate for x. x=32/4, which equals 8, so x=8
Next, substitute 8 for x in the equation x+y = 4.
Then, solve the equation for y.
x+y=4 given equation
8+y=4 substitute 8 for x
8-8+y = 4-8 subtract 8 from both sides of the equation
y= -4

First find x. X=32/4, so x=8
substitute 8 for x in the equation
x+y=4
8+y=4
-8 -8
y= -4
