Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

\(y = x + 3\) is a linear equation and \(y = x^2 + 3x\) is a quadratic equation. If the product of two numbers is zero, then one or both numbers must also be equal to ...

We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions. or \(x=100 ...

Systems of equations can be modelled as matrices in order to solve them The concept and example illustrated below explain the calculations that occur: $$ A \begin ...

Where λ & y are individual coefficients, the no. of equations = no. of coefficients - 1 Note in order to work there must exist 1 equation where all instances of λ and y != 0 ...

I have been working on the simultaneous equations, a new task, for a week. I was able to understand it and solve the questions on the book. It was a good start of the year 2025. I hope that I will be ...
