Question

"five times the sum of a number and 6 is 48"

Answer 1

5 (x+6)=48

x=3.6

Explanation:

let x be the unknown number :

5 (x+6)=48

5x+30=48

5x=48-30

5x=18

x=18/5=3.6

Answer 2

Sum of the number is 8.4

Explanation:

x = sum of a number

(5 × x) + 6 =48

5x + 6 = 48

5x + (6 - 6) = (48 - 6)

5x = 42

5x ÷ 5 = 42 ÷ 5

x = 8.4
