Linear Equation in 2 variables

Last updated at April 16, 2024 by

A linear equation in 2 variables is like

  3x + 4y = 10

It has

  • An equal sign =
  • Highest power is 1
  • Two variables - x & y

 

Is 3y + 4z = 80 a linear equation in two variable?

Yes,

  It has

  • An equal sign =
  • Highest power is 1
  • Two variable - x & y

 

Is 3x + 4y + 5z = 50 a linear equation in two variable?

No

It has 3 variables - x, y, z.

But in linear equation in two variables, we have 2 variables.


Is 2x + 5 = 0 a linear equation in two variable?

No

It has 1 variable - x

But in linear equation in two variables, we have 2 variables.
