Question

Which is a solution to the equation |10-5y| = 20

Answer 1

The correct answer option is a) y =2.

Explanation:

We are given the following equation and we are to find the solution of this equation:

`| 1 0 - 5 y | = 2 0`

Here, the expression
`10-5y` is given in a modulus, which means that its value cannot be negative.

`1 0 - 5 y = 2 0`

`-5 y = 2 0 - 1 0`

`-5 y = 1 0`

Ignoring the negative sign because of mod.

`y=(10)/(5)`

y = 2
