Question

1.6b - 8b - 17.28= -5.7b - 14.83

b= ?

Answer 1

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
