Math Problem Statement

Solve for x and y: 3x+2y=12

Solution

To solve the equation 3x+2y=123x + 2y = 12 for xx and yy, we can express one variable in terms of the other. Let's solve for yy in terms of xx:

  1. Start with the equation: 3x+2y=123x + 2y = 12

  2. Subtract 3x3x from both sides: 2y=123x2y = 12 - 3x

  3. Divide both sides by 2 to solve for yy: y=123x2y = \frac{12 - 3x}{2} y=63x2y = 6 - \frac{3x}{2}

So, the solution in terms of xx is y=63x2y = 6 - \frac{3x}{2}.

If you'd like to find specific values of xx and yy, you can choose a value for xx and substitute it into the equation to solve for yy, or vice versa. However, with just one equation, xx and yy are dependent on each other and can have infinitely many solutions.

  2. What happens if we assign specific values to xx or yy in this equation?
  3. How would the graph of this equation look in the coordinate plane?
  4. Can we solve this problem using matrix methods?
  5. How does substitution compare to elimination in solving systems of equations?

Tip: Always check your solution by substituting the values back into the original equation to ensure they satisfy it.
