Question

Write an equation using x when the sum of a number and 8 is multiplied by 3and the answer is 6

Answer 1

3(x + 8) = 6

Explanation:

let the number be x then the sum of x and 8 is x + 8 and multiplied by 3 is

3(x + 8) = 6 ( divide both sides by 3 )

x + 8 = 2 ( subtract 8 from both sides )

x = - 6

the number x is - 6
