Question

If x=3 what is the value of y in this equation?

Y=12x



a. 123
b. 36
c. 3
d. 15

Answer 1

`\displaystyle \large{y=36}`

Explanation:

We are given the equation
`\displaystyle \large{y=12x}`. To find y-value when or at x = 3, simply substitute x = 3 in which gives us
`\displaystyle \large{y=12(3)}` then evaluate the value as we obtain the y-value or final answer to the question:

`\displaystyle \large{\boxed{y=36}}`
