Ok I have been trying to figure these 3 problems out and I know its probably something very simple as I can do other problems like them that are similar but these are racking my brain please help!
1. Write a system of equation where the solution is (-2,1)
2. This i need to find out x and y through elimination and/or substitution (same with #3):
4x+6y=18
6x+9y=18
3. 2/3x+y=-3
y-1/3x=6
Also, I can't seem to find the problem again but could someone give me insight on this one below as well? No one I have asked offline seems to know.
Probably can't get it completely right since im typing it by memory.
#4
Write the system of equation for this word problem:
Susie has $900 startup cash, each shirt she makes costs $20 to make. She plans on selling them for $30, how many shirts will it take for her to make a profit? (<--that is also part of the problem)
A) above question
B) write a system of equation showing the details of the word problem.
C) make a graph for the system of equation.
If anyone can help TY SO MUCH!
