You can put this solution on YOUR website! Solve for x: log(3x+7)+log(x-2)=1 ----(1) log[(3x+7)(x-2)] =1 using log(a) + log(b) = log(ab) all to the same base 10

1000 = (3x-1)/2 multiply both sides of this equation by 2 to get: 3x-1 = 2000 add 1 to both sides of the equation to get: 3x = 2001 divide both sides of the equation by 3 to get: x = 667 that's your solution. when x = 667, log(3x-1) - log(2) = 3 becomes log(3*667-1) - log(2) = 3 which becomes 3 = 3. this confirms the solution is correct.
