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:
[tex] | 1 0 - 5 y | = 2 0 [/tex]
Here, the expression [tex]10-5y[/tex] is given in a modulus, which means that its value cannot be negative.
[tex] 1 0 - 5 y = 2 0 [/tex]
[tex] -5 y = 2 0 - 1 0 [/tex]
[tex] -5 y = 1 0 [/tex]
Ignoring the negative sign because of mod.
[tex]y=\frac{10}{5}[/tex]
y = 2
