how to make linear equations working model – tlm – maths working model

Linear equations are algebraic equations that represent straight lines on a graph. They are called “linear” because their highest power of the variable(s) involved is

1. The general form of a linear equation in one variable (x) is:

ax + b = 0

where ‘a’ and ‘b’ are constants, and ‘x’ is the variable. The solution to a linear equation in one variable is a single value of ‘x’ that makes the equation true.

Examples of linear equations in one variable:

  1. 2x – 3 = 0
  2. 4x + 7 = 15
  3. -3x + 2 = -8

When graphed on the coordinate plane, a linear equation in one variable forms a straight line.

Linear equations can also involve more than one variable and are called “linear equations in two variables” or “simultaneous linear equations.” The general form of a linear equation in two variables (x and y) is:

ax + by = c

where ‘a,’ ‘b,’ and ‘c’ are constants, and ‘x’ and ‘y’ are the variables. The solution to a system of two linear equations is the values of ‘x’ and ‘y’ that satisfy both equations simultaneously, making them true.

Examples of linear equations in two variables:

  1. 2x + 3y = 10
  2. 4x – 5y = 8
  3. -3x + 2y = -6
