Respuesta :
Equation R: -3y = -3x - 9
Equation S: y = x + 3
Replace y in Equation R with equation S:
-3(x+3) = -3x - 9
Use distributive property:
-3x -9 = -3x -9
Because both sides of the equation are identical x can be any number and they would still be equal.
This means there are Infinite solutions.
Let's solve the system of equations with the substitution method
Equation R: -3y = -3x - 9
Equation S: y = x + 3
Substitute y in Equation R with equation S:
-3(x+3) = -3x - 9
-3x -9 = -3x -9
Because both sides of the equation are identical x can be any number and they would still be equal.
This means there are Infinite solutions.
