Final answer:
The solution (-3, 5) does not satisfy any of the given equations in the system.
Step-by-step explanation:
To find the solution of the system of equations y = -x - 10 and 3x + 15y = 19 as (-3, 5), we need to substitute the values of x and y into the equations. Let's start with equation (a):
y = -x - 10
Substituting x = -3 and y = 5:
5 = -(-3) - 10
5 = 3 - 10
5 = -7
The values do not satisfy equation (a). Therefore, the solution (-3, 5) is not a solution to the given system of equations.
Similarly, substituting the values into equations (b) and (d) will also not yield the solution (-3, 5). Therefore, there is no way to complete the equations so that the solution of the system of equations is (-3, 5).
