[tex]\frac{-a}{10} -8=-24[/tex] Add 8 on both sides
[tex]\frac{-a}{10}-8+8=-24+8[/tex]
[tex]\frac{-a}{10}=-16[/tex] Multiply 10 on both sides
[tex](10)\frac{-a}{10}=-16(10)[/tex]
-a = -160 Divide -1 on both sides
[tex]\frac{-a}{-1}=\frac{-160}{-1}[/tex]
a = 160
[proof]
[tex]\frac{-a}{10} -8=-24[/tex]
[tex]\frac{-160}{10} -8=-24[/tex]
-16 - 8 = -24
-24 = -24
