Math Problem Statement
Solve the system of linear equations:
\[
\begin{cases}
y = 2x + 1 \\
2x - y = 3
\end{cases}
\]
Solution
This is a system of linear equations:
y = 2x + 1 \\ 2x - y = 3 \end{cases}$$ To solve this system, we can use substitution or elimination. I’ll use substitution here since $$y$$ is already isolated in the first equation. 1. Substitute $$y = 2 \ \ (2x + 1)$$ from the first equation into the second equation: \[ 2x - (2x + + 1)Ask a new question for Free
