It is a linear equation in one variable, x.
the answer is -3x = 0
The answer to your question, as asked, is that it is a linear equation with one variable, x. 3x + 3 = 9 Subtract 3 from both sides: 3x = 6 Divide both sides by 3: x = 2
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
4x + 2 = 3x + 9 x + 2 = 9 x = 7
50, 53, 59
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
X equals 9.
4x+6-7x+9=18-3x+15=18-3x=3x=-1
3x+2y=9 2y=9-3x y=-1.5x-4.5
The answer is -8.
3x+14 = 23 so 3x = 9 and so x = 9/3 = 3
