Answer:a) W=-17x/-5
Step-by-step explanation:
Number of books = x
6W-(X×17)=W
6W -17X = W
Collect like terms
-17X= W-6W
-17X = -5W
Divide both sides by the coefficient of W
-17X÷ -5 = -5W÷ -5
W = -17X÷ -5
B) W = 34
W = -17X ÷ -5
34 = -17X ÷ -5
Cross multiply
-17X = 34× -5
-17X = -170
Divide both sides by the coefficient of X
X = -170 ÷ -17
X = 10
∴ Angela bought 10 books
