Question

Help me by showing me the step

Answer 1

1. 15

Explanation:

I'll help you out with question #1 and follow these steps to help you with solving the rest of the problems.

1.
`(6-x)/(3) = y` and we know that
`y=-3`.

We can substitute
`y=-3` to the first equation.

`(6-x)/(3) = -3`

Multiply both sides by 3 to get rid of the fraction.

`6-x = -9`

Now you can solve for
`x`, for which the value is 15.
