the sum of doubling a number and 100 which totals to 160

Take this algebraic expression in pieces:

1. Let the number be n.
2. Double it, means we multiply n by 2: 2n
3. The sum of this and 100 means we add 100 to 2n: 2n + 100
4. The phrase which totals means we set 2n + 100 equal to 160

2n + 100 = 160 <-- This is our algebraic expression
