Solve the system of equations
y = –3x + 4
x + 4y = –6
AI Answer
We're given a system of two equations:
y = −3x + 4
x + 4y = −6
Step 1: Substitute the expression for y from Equation 1 into Equation 2
Since y = −3x + 4, plug that into the second equation:
x + 4(−3x + 4) = −6
Step 2: Simplify the equation
x − 12x + 16 = −6
−11x + 16 = −6
Step 3: Solve for x
−11x = −6 − 16
−11x = −22
x = 2
Step 4: Plug x = 2 back into the first equation to find y
y = −3(2) + 4 = −6 + 4 = −2
Final Answer: x = 2, y = −2
✅ Correct choice: C. x = 2, y = –2
