Answer:

Solution given;

|-3x-6|=15

since

mistake mode is we need to take both sigh either positive or negative

modulus makes the negative value positive

we can keep ± instead of modulus

±(-3x-6)=15

±(3x+6)=15

taking positive

3x+6=15

3x=15-6

x=9/3

x=3

Taking negative

-(3x+6)=15

-3x-6=15

-3x=15+6

-3x=21

x=21/-3

x=-7
