Respuesta :

As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.
Therefore, the system has infinite solutions.

The given equations have infinitely many solutions.

What is an equation?

  • An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.  
  • If there are two equations  ax + by + c = 0 , dx + ey + f = 0 and if [tex]\frac{a}{d}= \frac{b}{e} = \frac{c}{f}[/tex]  , then the equations are said to have infinite solutions.

How to know how many solutions does the system of equations have ?

The given equations are y= -2x +9 and 6x + 3y =27

Comparing with the standard equations we can see that,

  • a = 2
  • b = 1
  • c = -9
  • d = 6
  • e = 3
  • f = -27

∴  [tex]\frac{a}{d} =\frac{2}{6} = \frac{1}{3}[/tex]

∴   [tex]\frac{b}{e} = \frac{1}{3}[/tex]

∴  [tex]\frac{c}{f} = \frac{-9}{-27}= \frac{1}{3}[/tex]

∴  The conditions of [tex]\frac{a}{d}= \frac{b}{e} = \frac{c}{f}[/tex] is satisfied  and hence the equations have infinitely many solutions.
