That all depends.
Is it:
ln (2x+9) = ln (5x)
If it is, the solution can be found by solving 2x+9 = 5x, in which case the answer is x = 3.
x = -5
2x + 3 = 72x = 4x = 2
Not sure what you mean; that equation certainly has a solution.
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
x = 3 and y = 2
2x plus 3y
X = 6
x=2
x = 0
x = -5
x=-2
The answer is (3.5)2 plus (4)2 equals 410.
2x + 3 = 72x = 4x = 2
Not sure what you mean; that equation certainly has a solution.
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
1 solution
The solution is: x = 1 and y = -1
