    Infinitely many solutions. I will try to solve your system of equations. 3x + y = 9; 3x = - y + 9 Step: Solve 3x + y = 9 for y: 3x + y + - 3x = 9 + - 3x (Add - 3x to both sides) y = - 3x + 9 Step: Substitute - 3x + 9 foryin 3x = - y + 9 : 3x = - y + 9 3x = - ( - 3x + 9) + 9 3x = 3x (Simplify both sides of the equation) 3x + - 3x = 3x + - 3x (Add - 3x to both sides)

    so ur answer is

    Infinitely many solutions.
