No reason, or no evidence to support your claim/proof
The factored form would be (3x-9)(x-1)
The picture should help a bit
-6y + 14 + 4y = 32 Combine like terms (-6y and 4y)
-2y + 14 = 32 Subtract 14 from both sides
-2y = 18 Divide both sides by -2
y = -9
What is the system that you have to solve to find the value of x and y?
