Answer
To estimate the solution for the equation 3y + 2x = rac{1}{2}, first locate the intersection point of the graph representing this equation on the grid. The estimated coordinates of this point appear to be approximately (0.5, -0.5).
Step 2
2y - 3x = rac{113}{12}

Answer
Next, for the equation 2y - 3x = rac{113}{12}, identify its graph and find where it intersects with the previous graph. The estimated coordinates for this intersection point are approximately (2, 2.5).
