To solve the system of equations:
- \(3x + y = 2\) (Equation 1)
- \(7x - 4y = 30\) (Equation 2)
We can use substitution or elimination. Let's use substitution with Equation 1.
From Equation 1, solve for \(y\):
\[y = 2 - 3x\]
Now, substitute \(y\) in Equation 2:
\[7x - 4(2 - 3x) = 30\]
Now distribute the \(-4\):
\[7x - 8 + 12x = 30\]
Combine like terms:
\[19x - 8 = 30\]
Add 8 to both sides:
\[19x = 38\]
Now, divide by 19:
\[x = 2\]
Now that we have \(x\), substitute back into the expression for \(y\):
\[y = 2 - 3(2)\]
\[y = 2 - 6\]
\[y = -4\]
Thus, the solution to the system of equations is:
\((2, -4)\)
Therefore, the correct response is:
\((2, -4)\)
