1 answer

To solve the system of equations using substitution, we can start with the two given equations:

  1. \( y = 2 + 3x \)
  2. \( 4x - 3y = -16 \)

First, substitute the expression for \( y \) from the first equation into the second equation.

Substituting \( y \) in the second equation:

\[ 4x - 3(2 + 3x) = -16 \]

Now, simplify the left side:

\[ 4x - 6 - 9x = -16 \]

Combine like terms:

\[ -5x - 6 = -16 \]

Now, add 6 to both sides:

\[ -5x = -10 \]

Next, divide both sides by -5:

\[ x = 2 \]

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

\[ y = 2 + 3(2) = 2 + 6 = 8 \]

Thus, the solution to the system of equations is \( (x, y) = (2, 8) \).

Therefore, the correct answer is:

(2, 8)
