1st we combine like terms
1.6b minus 8b which equals -6.4b
Now right out your new expression
-6.4b - 17.28 = -5.7b - 14.83
Now add 5.7 to both side
-6.4b - 17.28 = -5.7b - 14.83
+5.7b +5.7b
This should get you what bellow and then add +17.28 to both sides
-0.7b - 17.28 = -14.83
+17.28. +17.28
Almost done..
Now you're left with
_-0.7b___ = _2.45___
-0.7b. -0.7b
Answer= -3.5
This app messed up the order of the numbers so I hope you can understand where things go
