log_{10}(5x)=log_{10}(2x+9)

lo g_{10} (5 x) = lo g_{10} (2 x + 9)

x = 3

Solution steps

lo g_{10} (5 x) = lo g_{10} (2 x + 9)

Apply log rules

5 x = 2 x + 9

Solve

5 x = 2 x + 9 : x = 3

x = 3

Verify Solutions:

x = 3

True

The solution is

x = 3

lo g_{5} (x + 10) + 7 = 9

lo g_{b} (100) = 3

lo g_{2} (3 x + 4) = 5

lo g_{10} (5 x^{2} - 21 x) = \frac{2}{5}

2 lo g_{10} (x) - lo g_{10} (x + 6) = 0
