Question

Determine if the point (16,5) is a solution to the equation x-9y=12?

Answer 1

Our answer is: It's not a solution.

`\Large\texttt{Explanation}`

We are asked to determine if the point (16,5) is a solution for the equation
`\sf{x-9y=12}`.

So what we do is we plug in 16 for x, and 5 for y -

16 - 9(5) = 12

16 - 45 = 12

-29 = 12

Obviously this is a false statement, which means that (16,5) is not a solution to the equation x - 9y = 12.

Answer 2

not a solution

Explanation:

to determine if the point (16, 5 ) is a solution to the equation.

substitute x = 16 and y = 5 into the left side of the equation and if the result is equal to the right side then it is a solution.

x - 9y = 12

left side = x - 9y = 16 - 9(5) = 16 - 45 = - 29 ≠ 12

Then (16, 5 ) is not a solution to the equation
