Question

Is 9y+9x=18 a linear equation?

Answer 1

Answer:

9x-9y=-18;9y-9x=18

This deals with linear equations with two unknowns.

Step-by-step explanation:

System of Linear Equations entered :

[1] 9x-9y=-18

[2] 9y-9x=18

Equations Simplified or Rearranged :

[1] 9x - 9y = -18

[2] -9x + 9y = 18

Solve by Substitution :

// Solve equation [2] for the variable y

[2] 9y = 9x + 18

[2] y = x + 2

// Plug this in for variable y in equation [1]

[1] 9x - 9•(x +2) = -18

[1] 0 = 0 => Infinitely many solutions

Infinitely many solutions
