Math Problem Statement

2x+3y=12

Solution

The equation given is:

2x+3y=122x + 3y = 12

This is a linear equation in two variables, xx and yy. You can solve this equation for one variable in terms of the other, or if given additional information (like another equation), you could solve for both xx and yy.

Solving for yy in terms of xx:

3y=122x3y = 12 - 2x

Now, divide by 3:

y=122x3y = \frac{12 - 2x}{3}

This simplifies to:

y=423xy = 4 - \frac{2}{3}x

Thus, yy is expressed in terms of xx.

Solving for xx in terms of yy:

2x=123y2x = 12 - 3y

Now, divide by 2:

x=123y2x = \frac{12 - 3y}{2}

This simplifies to:

x=632yx = 6 - \frac{3}{2}y

Thus, xx is expressed in terms of yy.

Would you like more details on how to graph this or solve it further with specific values?
