Math Problem Statement

4 x plus 3 y equals 12

Solution

The given equation is:

4x+3y=124x + 3y = 12

This is a linear equation in two variables, xx and yy. Here's what we can do with this equation:

Solve for yy in terms of xx:

  1. Subtract 4x4x from both sides: 3y=124x3y = 12 - 4x
  2. Divide both sides by 3 to solve for yy: y=124x3y = \frac{12 - 4x}{3} Simplifying the right-hand side: y=443xy = 4 - \frac{4}{3}x

So, y=443xy = 4 - \frac{4}{3}x is the equation in slope-intercept form (y=mx+by = mx + b), where the slope is 43-\frac{4}{3} and the y-intercept is 4.

Would you like to solve for xx in terms of yy, graph the equation, or ask anything specific about this equation?

Here are 5 related questions you might find useful:

  1. How do we find the slope of a line from a linear equation?
  2. What is the interpretation of the slope in a linear equation?
  3. How can we determine the x- and y-intercepts from this equation?
  4. Can we solve this equation using substitution or elimination with another equation?
  5. How would we graph this equation step-by-step?

Tip: The slope tells you how much the value of yy changes for every unit increase in xx.
