Answer:
60 books
Step-by-step explanation:
let the number of books Willy has be x , then
Tammy has 4x books
Willy has 180 fewer books , that is Tammy has 180 more than Willy , so
4x = x + 180 ( subtract x from both sides )
3x = 180 ( divide both sides by 3 )
x = 60
Thus
Willy has 60 books andTammy has 4 × 60 = 240 books
which is 180 more than Willy
Answer:
x = -4
x = 6
Step-by-step explanation:
x² - 2x -24 = 0
x² - 6x + 4x - 24 = 0
x ( x - 6 ) + 4 ( x - 6) = 0
x + 4 and x- 6
so either of them is zero so values if x are
X = -4
X = 6
