Jasmine Chai Grade 10 196298501 Patterns within systems of linear equations Systems of linear equations are a collection of linear equations that are related by having one solution‚ no solution or many solutions. A solution is the point of intersection between the two or more lines that are described by the linear equation. Consider the following equations: x + 2y = 3 and 2x – y = -4. These equations are an example of a 2x2 system due to the two unknown variables (x and y) it has. In one of

Linear equations As we have seen‚ a linear equation with n different variables‚ say x1‚ x2 ‚ x3‚...‚ xn ‚ can always be written in the equivalent standard form a1 x1 + a2 x2 + a3 x3 +... + an xn = c ‚ where c is a constant‚ the xi are the unknowns and the ci are coefficients. Here are some examples: 5x − 3y = z + w − 6 is a linear equation with
