Based on the provided information about the equations of the lines and their intersection point, the solution to the system of equations \( y = 5x + 10 \) and \( y = -2x + 3 \) can be found at the point where the two lines intersect. According to the description, the lines intersect at the point \( (-1, 5) \).
Therefore, the estimated solution to the system of these linear equations is:
(−1, 5) (left parenthesis negative 1 comma 5 right parenthesis).
