Algebra: Linear equations and inequalities
Welcome back to my blog! Today, we're continuing our journey into the world of algebra. Many problems in math can be solved using equations. We convert word problems into algebraic equations by representing unknown quantities with variables such as "x." We then follow a formal procedure to find the solution. A linear equation typically takes the form ax+b=0, where x is a variable "a" and "b" are constants, and a ≠ 0 . Examples of linear equations include 3x-2=4 and 2x+1=9. Note : There is a crucial difference between equations and expressions. Expressions are representations of mathematical statements that are not equated to anything, while equations are expressions equated to something. In other words, there's an equal to(=) sign in equations but there's no equal to(=) sign in expressions. Sides of an Equation Every equation has two sides: the left-hand side (LHS) and the right-hand side (RHS). For example, in the equation 3x+4=9 LHS: 3x+4 ...
