Answer:
2x+ 2y = -2
Step-by-step explanation:
Given the equation of a line as x + y = -1
To get the equation of the line P so the set of equations has infinitely many solutions, we will have to multiply the given equation by a factor
Multiplying the given equation by a factor of 2;
Given x + y = -1
Multiplying both sides by 2;
2(x + y) = 2(-1)
2x+ 2y = -2
Hence the required equation is 2x+ 2y = -2
