Question

The population of Glendale this year is 3,200 more than half of last year's population. The population this year is 26,300. Which equation could be solved to find last year's population?

Answer 1

2 × (26,300 - 3,200) 

If the population is 3,200 more than half of last year's, you can subtract 3,200 to get half of last year's. Then, just multiply by two to double it (because 2 × 1/2 is a whole or 1)

Hope this helps!
