Problem

Solve the following system of equations using the elimination method. \[ \begin{array}{c} \left\{\begin{array}{l} 6 x-2 y=-4 \\ 3 x+y=4 \end{array}\right. \\ \left(\frac{[?]}{3},[]\right) \end{array} \]

Solution

Step 1 :Multiply the second equation by 2 to get \(6x + 2y = 8\)

Step 2 :Add the two equations together to get \(12x = 4\)

Step 3 :Divide both sides by 12 to solve for x, giving \(x = \frac{1}{3}\)

Step 4 :Substitute \(x = \frac{1}{3}\) into the second equation to get \(3*\frac{1}{3} + y = 4\)

Step 5 :Simplify to get \(y = 3\)

Step 6 :\(\boxed{The solution to the system of equations is \left(\frac{1}{3}, 3\right)}\)
