Question 30(a): Let x be the price of one pencil (in Ksh). A pen costs Ksh 4 more than a pencil. i) Write an expression for the price of one pen. ii) Write an expression for the price of one pencil.

Here's a step-by-step solution for Question 30: Question 30(a): Let x be the price of one pencil (in Ksh). A pen costs Ksh 4 more than a pencil. i) Write an expression for the price of one pen. Price of one pen = x + 4 ii) Write an expression for the price of one pencil. Price of one pencil = x Question 30(b): The question states: "Above and hence solve for x." However, no equation is provided in part (a) or explicitly stated in part (b) that allows us to solve for x. Without an equation, x
