You cannot solve log x- 2 unless (i) log x - 2 is equal to some number or (ii) x is equal to some number.
Set it equal to 0 and subtract x and solve for y
You would set the equation equal to 0 and then solve for x. You may get one or several answers for x, x being the number(s) that make the equation equal 0.
x / (x+1) is an already simplified term. In order to "solve" it, you must either know the value of x, or set the entire term equal to some number.
3/14 = X/84 Cross multiply the proportion: 14X = 252 X = 252/14 = 18.
If you set a function equal to zero and solve for x, then you are finding where the function crosses the x-axis.
Nine hundred and seventy five. Just solve for "?" in this equation: 1/300 = 3.25/?. You get ? = 3.25 x 300, which is 975
x >/= 12
There is not enough information to solve for x. x+5x+15 must equal something (is it 0?) in order to solve for x.

You cannot since it has no solution.
u can't solve it because there has to be one variable to solve and equal sign, ex. 4x=20. U can simifly though distrubute the n to 4 and -x. ur answer is 4n-nx
