hi i was wondering how to enter this sum in to sage , when a quantity of liquid is heated in a insulated container, its final temperature (T=degrees) is given by T=T0+kt where T0 is the original temp , t (min) is the duration of heating and k is a constant. For a particular mass of a particular liquid, it is found that after heating for 2 mins its temp is 35degrees and after heating for a total time of 7mins its temp is 50degrees the question i need to solve is - form a pair of simultaneous equations and solve them to find the original temperature of the liquid and the value of the constant k
