Question

Eighteen is fifteen less than the product of a number and three .Find the number

Answer 1

Answer:

x = 11

Explanation:

(x · 3 - 15) = 18

[ Step 1: Simplify both sides of the equation ]

x(3) − 15 = 18

3x + −15 = 18

3x − 15 = 18

[ Step 2: Add 15 to both sides ]

3x − 15 + 15 = 18 + 15

3x = 33

[ Step 3: Divide both sides by 3 ]

3x / 3 = 33 / 3

x = 11
