-4(0.25b-2) - (7 - b) + 3/2 (4b - 2/3)
We must open the parenthesis first by multiplying the elements in it be the elements outside
Bearing in mind that
- * - = +
- * + = -
-4(0.25b-2) - (7 - b) + 3/2 (4b - 2/3)
= -b - 8 -7 + b + 6b - 1
Now we rearrange so all like terms are together noting the signs before each term
= -b + b + 6b - 8 - 7 - 1
= 6b - 16
You may leave the answer in this form or go further to factorize
= 2 (3b - 8)
