Question

What is the value of y when x = 3. y = 12x

Answer 1

We have the equation y = 12x. And we know the value of x. The value of x is 3.
So, if we replace the x variable with the value of x, then we can solve the equation.

y = 12(3)
y = 36

So, the answer is 36.

Answer 2

y= 12 (x)
If x = 3 then,
y = 12 (3)
= 36
