8x=4y=12
This makes no sense.
8x=4y=12
I suspect you mean 8x + 4y = 12 or 8x - 4y = 12
If 8x + 4y = 12, y = 3 - 2x from which you get
x = <<-3...-2...-1...0...1...2...3 >
y = 9....7....5...3...1..-1..-3 ..
or an ifinite number os solutions.
If, by chance, you are seeking positive solutions only then,
x = 0 or 1 for
y = 3 or 1 respectively.
I'll let you work out the 8x - 4y - 12 case.
8x+4y=12
The equation you provided, 8x = 4y = 12, appears to be incorrect or improperly formatted. In an equation, we typically use a single equal sign (=) to represent that both sides of the equation are equal. Multiple equal signs in an equation are not valid.
To solve an equation, we usually need one unknown variable to work with. In your equation, there are two variables, x and y, and it is not clear how they are related to each other or to the constant value 12.
If you can provide a correctly formatted equation or clarify the relationship between x and y, I will be happy to help you solve it.
