Solve the system of equations by any method. \[ -3 x+12 y=9 \] Enter the exact answer as an ordered pair, \( (x, y) \). If there is no solution, enter NS. If there is an infinite number of solutions, enter the an ordered pair in terms of \( x \). Include a multiplication sign between symbols. For example, \( a \) * \( x \). NS

The solution is \( (x, \frac{3 + x}{4}) \).

Solución

The system of equations provided is not in the correct format for solving. Let's rewrite the system of equations as a system of two equations: \[ -3x + 12y = 9 \] To solve this system of equations, we can use any method such as substitution, elimination, or graphing. Let's solve it using the elimination method. First, we can multiply the first equation by 3 to make the coefficients of \( x \) in both equations the same: \[ -9x + 36y = 27 \] Now, we can add the two equations to eliminate the variable \( x \): \[ (-9x + 36y) + (-3x + 12y) = 27 + 9 \] \[ -12x + 48y = 36 \] Now, we can solve for \( y \) in terms of \( x \): \[ 48y = 36 + 12x \] \[ y = \frac{36 + 12x}{48} \] \[ y = \frac{3 + x}{4} \] Therefore, the solution to the system of equations is \( (x, y) = (x, \frac{3 + x}{4}) \).

To solve the system of equations, we start with the given equation: \[ -3x + 12y = 9 \] First, let's isolate \( y \) by manipulating the equation. We can add \( 3x \) to both sides: \[ 12y = 3x + 9 \] Next, we divide everything by 12 to solve for \( y \): \[ y = \frac{3}{12}x + \frac{9}{12} \] This simplifies to: \[ y = \frac{1}{4}x + \frac{3}{4} \] This equation represents a line in slope-intercept form, meaning it has infinitely many solutions for different values of \( x \). Therefore, we can express the solution as an ordered pair in terms of \( x \): \[ (x, \frac{1}{4}x + \frac{3}{4}) \]
