To solve the system of equations using substitution, we have the following equations:
1. \( y = 2 + 3x \)
2. \( 4x - 3y = -16 \)
We can substitute the expression for \( y \) from the first equation into the second equation.
**Step 1: Substitute for \( y \)**
Substituting \( y \) in the second equation:
\[
4x - 3(2 + 3x) = -16
\]
**Step 2: Distribute the \(-3\)**
\[
4x - 6 - 9x = -16
\]
**Step 3: Combine like terms**
\[
-5x - 6 = -16
\]
**Step 4: Add 6 to both sides**
\[
-5x = -10
\]
**Step 5: Divide by -5**
\[
x = 2
\]
**Step 6: Substitute \( x \) back into the first equation to find \( y \)**
Now we substitute \( x = 2 \) back into the first equation:
\[
y = 2 + 3(2)
\]
\[
y = 2 + 6 = 8
\]
**Step 7: Write the solution as an ordered pair**
The solution to the system of equations is:
\[
(x, y) = (2, 8)
\]
So the answer is \( (2, 8) \).
1. \( y = 2 + 3x \)
2. \( 4x - 3y = -16 \)
We can substitute the expression for \( y \) from the first equation into the second equation.
**Step 1: Substitute for \( y \)**
Substituting \( y \) in the second equation:
\[
4x - 3(2 + 3x) = -16

4x - 6 - 9x = -16
\]
**Step 3: Combine like terms**
\[
-5x - 6 = -16
\]
**Step 4: Add 6 to both sides**
\[
-5x = -10
\]
**Step 5: Divide by -5**
\[
x = 2
\]
**Step 6: Substitute \( x \) back into the first equation to find \( y \)**
Now we substitute \( x = 2 \) back into the first equation:
\[
y = 2 + 3(2)
\]
\[
y = 2 + 6 = 8
\]
**Step 7: Write the solution as an ordered pair**
The solution to the system of equations is:
\[
(x, y) = (2, 8)
\]
So the answer is \( (2, 8) \).
