The equation is on y and x. We need to prove X+Y=100
Step-by-step explanation:
If the value of X=40,
Then value of Y could be 100-40 because the total count is 100.
Y=60.
Verification done by the given equation.
X+Y=100
Y=100-X
Y=100-40
Y=60
Therefore the value of the Y is 60
The value of y from the given equation x + y = 100 when x = 40 is 60
x + y = 100
If
x = 40
substitute x = 40 into the equation
x + y = 100
40 + y = 100
y = 100 - 40
y = 60
Therefore, the value of y is 60 from the given equation
