10.2 Simultaneous Linear
So far, we looked at one linear equation; there are times when you are provided with two linear equations and you have to look for a solution. By solution we mean values of x and y that are common in both equations. There are two ways of solving these equations: Graphically and Algebraically.
Adam has a business of selling cars. The following linear equations define his revenue and costs.
Revenue = 27,000 × no. of cars sold
Cost = 150,000 + 12,000 × no. of cars sold
