Help me answer the questions please

(a) Solve the following differentlal equations: i) y2y8y=8x+3 ii) y5y2+6y=6et+1 b) Solte yn2y+y=x2+2cx QUESTION 2 (a) In a proposed chemical process a pure liguid A is fed to a batch reactor. The elementary equation below represents the reaction: If the concentration of the species at any given lime are CA,C2 and CC, find the: i. maximum concentration of B,CEw in terms of C40,k1,k2 and t ii. time to obtain a maximum concentration of B. QUESTION 3 (a) A large tank holds 400L of brine solution with 40kg of salt. A concentration of 2kgL is pumped in at a rate of 5L/min. a concentration leaving the tank is pumped out at a rate of 4 Limin, how much salt is in the tank after 10 mins? b) The steam pipe 30cm in diameter contains steam at 160C and is covered with a material 8cm thick. If the temperature of the outer surface of the covering is 30C, find the temperature half-way through the covering under steady state conditions (a) Solve the following differentlal equations: i) y2y8y=8x+3 ii) y5y2+6y=6et+1 b) Solte yn2y+y=x2+2cx QUESTION 2 (a) In a proposed chemical process a pure liguid A is fed to a batch reactor.
