X could be anything... you need an equals sign in there somewhere

Since you have listed and an expression, you cannot find a value for x. However, if you meant to include that the expression (2x-30)(x+60) = 0, then set each binomial equal to zero and solve for x.
a) 2x-30=0 and b) x+60 = 0
To solve equation a), add 30 to each side of the equation, then divide each side by 2. The solution is 15.
To solve equation b), subtract 60 to both sides, and the solution is -60.

2x-30=0
x+60=0
2x-30+30=0+30
2x=30
x=15 or -60

from the first parenthetical expression, 2x = 30; x=15
and from the second, x = -60

x= -60 or 15, that is, if the whole equation equals zero.
