2q-14
70-q-q-2q = 70-4q = 80-4q = 10q=-10/4 = -5/2 = -2.5
-q-11=2q+4 you would subtract 4 from both sides 4 and -4 cancel out and -11-4= -15 then you get -q-15=2q then you would add Q(1) to both sides (-q and q cancel out) then u get -15=3q thn u divide 3 to both sides (3 and 3 become q) then u get q=-5
simply add the like terms: 4p -3p +2q -2q = p
