Question

When 6 times a number y is subtracted from 15, the result is 33. what number results when 3 times y is added to 19?

Answer 1

Answer: 10

Explanation:

When
`6`
`y` is subtracted from
`15` we get
`33`. That can be expressed:

`15-6y=33`.

Solving that gives the following value.

`15-6y=33\\-6y=33-15\\-6y=18 \\y=-3`

Now there is
`y=-3`, and it is possible to find
`19+3y`.

Substitute
`y` and calculate the solution.

`19+3* (-3)=19-9=10`.
