Well if 3x+9=5 x=?
Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.

If 3x-5 equals 9 what is the value of x?
3x - 5 = 9 3x = 9 + 5 3x = 14 x = 14/3 or 4 2/3
3x-3 equals 2x plus 6?
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
5x plus 4 - 3x plus 5 plus 2x - 9?
5x + 4 - 3x + 5 + 2x - 9 = 4x
What is the answer to -2x to the 4 plus 16 plus 2x to the 4 plus 9-3x to the 5?
-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
Is 3x plus 2y equals 5 and 3x plus 2y equals 9 perpendicular or parallel?
We need to get both equations into slope-intercept form. If they are parallel, they will have the same slope. If they are perpendicular, they will have slopes that when multiplied equal -1. (unless one line is horizontal and the other vertical) 3x+2y=5 2y=5-3x y=(-3/2)x+(5/2) 3x+2y=9 2y=9-3x y=(-3/2)x+(9/2) The two lines are parallel, since both slopes are equal to (-3/2).
What is the answer to 7x-9 equals 3x plus 5?
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
What is the answer to 3x plus 9?
3x plus 9 equals what?
What is the algebraic expression answer for 3x plus 5 equals 14?
3x+5=14 3x=9 x=3
What does x equal in 5 equals -4 plus 3x plus 4?
x= 1.67(rnd) 5= -4+3x+4 5- -4= 9 9=3x+4 9-4=5 5=3x x= 1.67(rnd)
What is the answer to 3x plus 4 equals 4x-5?
3x + 4 = 4x - 5 Add 5 to both sides: 3x + 9 = 4x Subtract 3x from both sides: 9 = x
What is the answer to negative 6x plus 9 equals 9-3x?
the answer is -3x = 0
What is the variable for 3x plus 5 equals 14?
3x+5=14 3x+5-5=14-5, -5 on both side 3x=9 (3x)/3=9/3, dividing by 3 on both side, so x=3
What is the value of 5x - 3x plus 5 when x equals 2?
10-6+5 = 9
What is the answer of 3x-1 plus 10 equals 5?
3x-1+10 = 53x + 9 = 53x = 5 - 93x = -4x = -4/3
What is 7x - 9 equals 3x plus 5?
It is a linear equation in one variable, x.
-3x plus 2y equals 9?
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
4x plus 2 equals 3x plus 9?
4x + 2 = 3x + 9 x + 2 = 9 x = 7
