x−6y=22
(1 point)

1 answer

To solve the system of equations:

  1. \( 5x + 2y = 14 \) (Equation 1)
  2. \( x - 6y = 22 \) (Equation 2)

We can solve for one variable and substitute it into the other equation. Let's solve Equation 2 for \( x \):

\[ x = 6y + 22 \]

Now, substitute \( x \) into Equation 1:

\[ 5(6y + 22) + 2y = 14 \]

Distributing the 5:

\[ 30y + 110 + 2y = 14 \]

Combine like terms:

\[ 32y + 110 = 14 \]

Now, subtract 110 from both sides:

\[ 32y = 14 - 110 \] \[ 32y = -96 \]

Now, divide by 32:

\[ y = \frac{-96}{32} = -3 \]

Now, substitute \( y = -3 \) back into the expression we derived for \( x \):

\[ x = 6(-3) + 22 \] \[ x = -18 + 22 \] \[ x = 4 \]

Thus, the solution to the system of equations is:

\[ (x, y) = (4, -3) \]
