Question 21759
let x equal oklahoma's population
let x - 187,000 equal new york population
let x- 187,000+ 22,000 equal North carolina

(x-187,000)+ (x-187,000 + 22,000)+ x = 437,000
3x - 352,000 = 437,000
3x=352,000+437,000
3x=789,000
x=263,000  ok population
plug x answer into other problems
263,000-187,00=76,000  New yorks population
263,000-187,000+22,000 = 98,000 North Carolina population
check answer
263,000 + 76,000 + 98,000 = 437,000
