Honestly I think that it’s c but check that and get back to me
2r-6+5r=3-r+7
7r-6=10-r
7r+r=10+6
8r=16
r=16/8
r=2
you move first the number without the variable to the other side with the opposite sign
-0.75p=0.25+2
-0.75p=2.25
then as -0.75 is multiplying you pass it to the other side dividing
p=2.25/-0.75
p=-3
Domain is (-10, infinity) and range is negative infinity, positive infinity.
