The expression of the form Ax B where A and B are real numbers and A 0 is a linear polynomial and equation involving only linear polynomial are called linear equations. The following are examples of linear equations. Solving linear equations and linear inequalities Harder example.
Use the first two facts above to get all.
M s 40 equation 1. Y 2x 1. M 10 2s 20. To solve the system of equations you need to find the exact values of x and y that will solve both equations.
