Tanner is 3 years younger than his sister lexi the sum of the siblings ages is 33 how old are tanner and lexi

tanner is 15 and lexi is 18

Step-by-step explanation:

I subtracted 3 from 33 and divided by two. That gave me tanners number, then added 3 to 15, which is 18, and also lexis age.

25% is the answer

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
