a grandmother says her grandson is two years older years older than her ganddaughter and that together , they are at least 12 years old. How old are her grandson and granddaughter? This is a inequality word problem
let x represent granddaughter and x +2 for grandson and together they = 12 so then we have the equation of x+2+x = 12 combine like terms 2x +2 =12 -2 from both sides to isolate x 2x=10 divide both sides by 2 to get x by itself so we get x = 5 then add 2 +5=7 so grandson is 7 and granddaughter is 5
