MY SISTER IS 7 YEARS OLDER THAN ME. MY BROTHER IS 3 YEARS YOUNGER THAN ME AT ANY AGE. WHAT EXPRESSION WOULD REPRESENT THE COMBINED AGES?

Iam stuck on one problem. my mind is in absoloute vacation mode. i literallty just need to finish this to be done will give brainliest and all my points if i have to! 1- point free throw and 2- point feild goal. he made 35 shots, and scored 62 points how many of each shot did he make in 1 minute? (i already did the math. he made 8 1-point free throws and 27 2-point feild goals.) 1. write two equations for the problem. (i had a major brain fart.)

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Which inequality has a dashed boundary line when graphed ?
