Question

Translate this phrase into an algebraic expression.

67 decreased by twice a number
Use the variable n to represent the unknown number.

Answer 1

2n-67

Explanation:

Twice a number means 'multiply by 2' so we can write 2 x n. We can also write this in a simpler form- 2n

'67 decreased' means minus 67 off your answer so therefore the answer must be:

2n-67
