Question

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

Answer 1

Answer:

The correct answer option is a) y =2.

Step-by-step 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.

$y=\frac{10}{5}$

y = 2
