Jeremy is 5 years younger than his older sister. His older sister is 9 years older than his younger sister. The total of their ages is 49.

Write and solve an equation to find the ages of Jeremy and his sisters.

Jeremy=x Older sister=x+5 younger sister=x+5-9 or x-4 x+(x+5)+(x-4)=49 combine like terms 3x+5-4=49 3x+1=49 subtract 1 from both sides 3x=48 divide both sides by 3 x=16 Jeremy=16 Older sister=16+5=21 younger sister =16-4 or 16+5-9=12 J=16 OS=21 YS=12

Jeremy is 16 years old, his older sister is 21 years old, and his younger sister is 12 years old. This was determined by forming equations based on their relationships and solving for their ages. The total of their ages sums to 49 years.
