Question

Twice a number x excced 5 by at least 4, find all possible value of X

Answer 1

x > 4.5

Explanation:

Twice a number x = 2 * x

must exceed 5 by at least 4 = 2 * x > 5 by at least 4 = 2* x > 5 + 4

Twice a number x (2*x) must exceed 5 (>5) by at least 4 (+4)

2* x > 5 + 4

2x > 9

divide both sides by 2 to isolate x

x > 4.5
