To solve the system of equations using the substitution method, we will substitute the expression for \(y\) from the first equation into the second equation.
We have the system:
1. \(y = 4x + 6\)
2. \(3x + 2y = 12\)
Now, substitute equation (1) into equation (2):
\[
3x + 2(4x + 6) = 12
\]
Now, simplify and solve for \(x\):
\[
3x + 8x + 12 = 12
\]
\[
11x + 12 = 12
\]
\[
11x = 12 - 12
\]
\[
11x = 0
\]
\[
x = 0
\]
Now that we have \(x = 0\), substitute back into the first equation to find \(y\):
\[
y = 4(0) + 6 = 6
\]
Thus, the solution to the system of equations is:
\[
(0, 6)
\]
So, the correct response is:
**(0, 6)**
