Here we break down everything you need to know about solving equations. You’ll learn what linear and quadratic algebraic equations are, and how to solve all the different types of them.At the end you’ll find solving equations worksheets based on Edexcel, AQA and OCR exam questions, along...
Concept of Linear Equations We will start off the solving portion of this chapter by solving these as linear equations. A linear equation is an equation which can be written in the form as given below: ax + b=0 where a and b are the numbers and x is a variable. This form is sometim...
You will need your algebra skills for solving equations with variables in them, so access that part of your brain right now so that you have that information at your disposal during this video lesson. We begin with a word problem. Tobias is scared that the banks will close on him, ...
Learn about multi-step equations. Understand what a multi-step equation is and how to solve it, see examples, and practice solving multi-step...
Simultaneous equations are two or more algebraic equations that share variables such as x and y. They are called simultaneous equations because the equations are solved at the same time. The number of variables in simultaneous equations must match the number of equations for it to be solved. ...
