[tex]\mathsf{a + (8)(c + b) + b}[/tex]
[tex]\mathsf{= a + 8(c + b) + b}[/tex]
[tex]\mathsf{= a + 8(c) + 8(b) + b}[/tex]
[tex]\mathsf{= a + 8c + 8b + b}[/tex]
[tex]\mathsf{= a + 8c + 9b}[/tex]
[tex]\mathsf{= -15 + 8(7) + 9(12)}[/tex]
[tex]\mathsf{= 41 + 9(12)}[/tex]
[tex]\mathsf{= 41 + 108}[/tex]
[tex]\mathsf{= 149}[/tex]
