Answer:

Sure, let's solve the system of equations using substitution.

Given:

\[x - 6y = -4\]

\[x = 2y + 4\]

Now, substitute the expression for \(x\) from the second equation into the first equation:

\[(2y + 4) - 6y = -4\]

Combine like terms:

\[2y - 6y + 4 = -4\]

Simplify:

\[-4y + 4 = -4\]

Subtract 4 from both sides:

\[-4y = -8\]

Divide by -4:

\[y = 2\]

Now that we have the value for \(y\), substitute it back into the second equation to find \(x\):

\[x = 2(2) + 4 = 8\]

So, the solution is the ordered pair \((x, y) = (8, 2)\).
