perfectly suited for substitution
2x + y = -8
2x + (2x+4) = -8
2x + 2x + 4 = -8
your turn, once you have the x, sub it back into y = 2x+4 for your y
Pls help me I need help!!!!For problems 1-4, solve the given system of equations using either substitution or elimination.

This concept rlly does not make any sense
I'm sorry to hear that you are struggling with this concept. Solving systems of equations using substitution or elimination can be tricky, but with practice and patience, it can be mastered. If you have any specific questions or examples you want to solve, feel free to ask and I'll be happy to help you.
I need help with it
Sure! Can you please provide me with a specific system of equations that you are struggling to solve using substitution or elimination method?
2x+5y=×
X-2y=x
X-2y=x
I believe there's a typo in the first equation. Can you please give me the correct value of "= x" in the first equation so I can solve the system for you?
2+5y=×
I think you missed giving me the value of "x" in the first equation again. Can you please provide me with the correct value of "x" in the first equation so I can help you solve the system of equations?
3x - 5y= -22
I need help too
Sure! What system of equations do you need help with?
3x - 5y = -22
What’s the answer bot
To solve the given system of equations using the substitution method, we can solve one equation for one variable and substitute it into the other equation. Here, we can solve the second equation for x as follows:
x - 2y = x
x = 2y
Now, substitute x = 2y into the first equation:
3x - 5y = -22
3(2y) - 5y = -22
6y - 5y = -22
y = -22
Finally, substitute y = -22 into x = 2y to get:
x = 2y
x = 2(-22)
x = -44
Therefore, the solution to the system of equations 3x - 5y = -22 is (x, y) = (-44, -22).
x - 2y = x
x = 2y
Now, substitute x = 2y into the first equation:
3x - 5y = -22
3(2y) - 5y = -22
6y - 5y = -22
y = -22
Finally, substitute y = -22 into x = 2y to get:
x = 2y
x = 2(-22)
x = -44
Therefore, the solution to the system of equations 3x - 5y = -22 is (x, y) = (-44, -22).
