Where I am having issues is what to do with the -2y. My professor did not go over what to do in that case. Please make work readable. Thank you for the help.
![**Solve by Substitution**
Given the system of equations:
1. \(2x + y = -1\)
2. \(-2y = -1 + 4x\)
Solution options:
- [ ] (Text Box for Input)
- [ ] No solution
- [ ] Infinite number of solutions
To solve the system by substitution, follow these steps:
1. Solve the first equation for \(y\):
\[
y = -1 - 2x
\]
2. Substitute this expression for \(y\) into the second equation:
\[
-2(-1 - 2x) = -1 + 4x
\]
3. Simplify and solve for \(x\) and \(y\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F306f2d1a-9f72-422e-b433-8de8d735b303%2Fa20c928a-cc43-4dec-8b77-63eb8e66eb1a%2Fobq5btb_processed.jpeg&w=3840&q=75)
