I need to be shown the process of doing these three problems so I can solve others like it, so when you solve them please try to show as much of the process as possible. solve the equation using substitution
x = y – 4

2x + 3y = 12

Solve the system using elimination.

2x – 3y = 16

x + y = 24

Solve the system using graphing.

x + y = 7

3x + 4y = 24
