Write down the system of equations clearly:
\[2x + y = 1\]
\[3x - y = 4\]
Add the two equations together to eliminate the variable \(y\). When you add them, the \(y\) terms cancel out because \(y + (-y) = 0\).
After adding, you will get an equation with only \(x\). Solve this new equation for \(x\) by isolating \(x\) on one side.
Substitute the value of \(x\) back into one of the original equations (either one works) to solve for \(y\).
Write the solution as an ordered pair \((x, y)\) representing the point where the two lines intersect.
