Question

please answer it..
solve by substition method... ​

Answer 1

Answer:

Step-by-step explanation:

3x-y=3;9x-3y=9

Infinitely many solutions

System of Linear Equations entered :

[1] 3x - y = 3

[2] 9x - 3y = 9

Solve by Substitution :

// Solve equation [1] for the variable y

[1] y = 3x - 3

for variable y in equation [2]

9x - 3•(3x-3) = 9

0 = 0 => Infinitely many solutions
