The required equation is (-9m) + (-10m) = -95 and the solution is m = 5.
The required sign for the sum is "+".
The sum of -9m and -10m is:
[tex]Sum=(-9m)+(-10m)[/tex]
It is given that the sum of -9m and -10m is -95.
[tex](-9m)+(-10m)=-95[/tex]
[tex]-9m-10m=-95[/tex]
[tex]-19m=-95[/tex]
Now, divide both sides by -19 to solve the equation.
[tex]\dfrac{-19m}{-19}=\dfrac{-95}{-19}[/tex]
[tex]m=5[/tex]
Therefore, the required equation is (-9m) + (-10m) = -95 and the solution is m = 5.
