The sum of five and eight times a number is the same as fifty plus one-half the number. How do you find the number?
1 Answer
Convert the statement into an algebraic equation and solve for the desired value.
Explanation:
Sum and plus = addition, Times = multiplication. Same = equals
Use ‘x’ as the unknown value.
5 + 8 * x = 50 + (1/2) * x
7.5x = 45 implies x = 6
CHECK:
5 + 8(6) = 50 + (1/2)(6)
5 + 48 = 50 + 3
53 = 53 -> CORRECT
