1 answer

We are given the system of equations:

  1. \(-x + 6y = 3\)
  2. \(-4x - 2y = -14\)

We can solve this system using the substitution or elimination method. Let's use the substitution method.

First, we can solve the first equation for \(x\):

\[ -x + 6y = 3 \implies x = 6y - 3 \]

Now, we can substitute this expression for \(x\) into the second equation:

\[ -4(6y - 3) - 2y = -14 \]

Expanding this gives:

\[ -24y + 12 - 2y = -14 \]

Combining like terms:

\[ -26y + 12 = -14 \]

Now, isolate \(y\):

\[ -26y = -14 - 12 \] \[ -26y = -26 \] \[ y = 1 \]

Now that we have \(y\), we can substitute back to find \(x\):

\[ x = 6(1) - 3 = 6 - 3 = 3 \]

Thus, the solution to the system of equations is:

\[ \boxed{(3, 1)} \]

To confirm, we can plug \(x\) and \(y\) back into both original equations.

For the first equation:

\[ -x + 6y = 3 \implies -3 + 6(1) = 3 \implies -3 + 6 = 3 \quad \text{(True)} \]

For the second equation:

\[ -4x - 2y = -14 \implies -4(3) - 2(1) = -14 \implies -12 - 2 = -14 \quad \text{(True)} \]

Both equations are satisfied, confirming that the solution \( (3, 1) \) is correct.
