Not sure what you are asking, clearly 6x is 3x plus 3x.
But the question asks "what is 3x equals 3x?"
"3x equals 3x" is a tautology.
(A logical tautology is a statement that is true regardless of the truth values of its parts)
If you are asking what the value of x is, this equation is true for any value of x.
All numbers are a solution of "3x equals 3x."
But the question is not very clear so please add some discussion to help?
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
-11
3x + 2 = -10 3x = -12 x = -4
3x - 4 = 73x = 11x = 3.66666...
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
