negative 70

anonymous · Answer

since you are trying to get the variable C itself, then we have to subtract 70 from the left hand side, but we must remember that what we do to one side of an equation must be done to the other side as well. Thus we subtract 70 from the right had side of the equation as well. This gives us c=-100
