There are an infinite number of them. The graph of that equation is a
straight line, and every point on the line is a solution of the equation.
Here are a few of them:
x= -3, y= -3
x= -2, y= 0
x= -1, y= 3
x= 0, t= 6
x= 1, y= 9
x= 2, y= 12
x= 3, y= 15
x=11, y= 39
x and y are both variables in this equation.
As one person already stated, the values cannot be found since there are two variables in the equation. We would need another equation to make a system in order to find the exact values. However, you could graph the line that represents this equation and find corresponding (x, y) values.

5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
3x+5x-2x = 24 6x = 24 x = 4
If: 3x-3 = 7x+21 Then: x = -6
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
If 3x - 9 = -6 then 3x must equal 3. Therefore x = 1 !
3x=18 x=18/3 x=6
3x = x + 4 x = 2 3x2=6 2+4=6
x = 4 and y = 6
First of all, if 'x' is 3, then 'x' doesn't equal -3x+3 . You must mean y = -3x + 3.If x=3, then (-3x + 3) = -6 .The graph is the point (3, -6) .
3x + 7 = -3x 6x = -7 x = -7/6
X= -2 ! Since the equation must equal zero - 17+3x must equal 11. The variable 3x HAS to equal -6... therefore x is equal to minus 2.
3x+12 = 18 3x = 18-12 3x = 6 x = 2
3x-4x=12 that means -x equals 12 so x equals -12
x = 6
3x + 6 = x - 10; subtract (x + 6) from each side to result in 2x = - 16; divide each side by 2 to result in x = -8.
If x equals 8, then 3x equals 24. 24-x would equal 16.
