1. Subtract the second equation from the first equation:
(X + 3y) - (X + 2y) = 4 - 4
X + 3y - X - 2y = 0
y = 0
2. Substitute
y = 0
into the second equation:
X + 2(0) = 4
X = 4
Correct [Solution]:
(4,0)

Exercise The temperature T in degrees Celsius of a chemical reaction is given as a function of time t, expressed in minutes, by the function defined on ¿ by: T (t )=(20 t +10)e−0.5t. 1) What is the initial temperature? 2) Show that T' (t )=(−10 t +15)e−0 .5t. 3) Study the sign of T' (t ), then draw up the table of variations of T . We do not ask for the limit of T in +∞. 4) What is the maximum temperature reached by the reaction chemical. We will give an approximate value to within 10−2. 5) After how long does the temperature T go back down to its initial value? We will give an approximate value of this time in minutes and seconds.
