im having trouble and i keep getting a wrong answer ? thanks

Evaluate the indefinite integral. dx/6 - 5x Part 1 of 4 We must decide what to choose for u. If u = f(x), then du = f'(x) dx, and so it is helpful to look for some expression in dx/6 - 5x = 1/6 - 5x dx for which the derivative is also present, though perhaps missing a constant factor. We see that 6 - 5x is part of this integral, and the derivative of 6 - 5x is which is simply a constant. If we choose u = 6 - 5x, then du = -5 dx. If u = 6 - 5x is substituted into dx/6 - 5x dx, then we have dx/6 - 5x dx = 1/u dx. we must also convert dx into an expression involving u. Using du = -5 dx, then we get dx = dx

Explanation / Answer

if u r suposing a variable u have to replace it in ur equation every were i.e. ike u=6-5x than by differetiating abve equation we get du=-5dx or dx=-(1/5) du which can be filled in the given space
