A linear equation is an equation with degree 1 - that is, the highest exponent on all variables in the equation is 1. Some examples of linear equations include: {eq}\begin{align*} &2x - 3 = 5\\ \\ &2x = 8 \\ \\ &y = 9x - 3\\ \\ &x/2 = 3\\ \\ &4x + 5y = 46...
This study examines eighth grade students' use of a representational metaphor (cups and tiles) for writing and solving equations in one unknown. Within this study, we focused on the obstacles and difficulties that students experienced when using this metaphor, with particular emphasis on the ...

An algebraic equation, such asy= 2x+ 7 or 3x+ 2y-z= 4, in which the highest degree term in the variable or variables is of the first degree. The graph of such an equation is a straight line if there are two variables. American Heritage® Dictionary of the English Language, Fifth ...
How do you write and solve linear equations? A linear equation is written in the form y = mx + c. There are two variables (x and y) and two constants (m and c). The constants need to be determined. When writing a linear equation we need to determine the two constants, just ...
