Please help Identify the LCD of the rational expressions in the equations

2/x+1 + x/x+4 = 1/2

4/x+9 + 3x/2x-1 = 10/3

I’d love it if anyone could answer both equations, but anything helps really!!!

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

14. (05.02 lc) what is the value of y in the solution to the following system of equations? (5 points) 2x + y = −4 5x + 3y = −6

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
