log_{10}(-x)+2=4

lo g_{10} (- x) + 2 = 4

x = - 100

Solution steps

lo g_{10} (- x) + 2 = 4

Move

2

to the right side

lo g_{10} (- x) = 2

Apply log rules

- x = 100

Solve

- x = 100 : x = - 100

x = - 100

Verify Solutions:

x = - 100

True

The solution is

x = - 100

12 = 20 lo g_{10} (\frac{x}{0.7})

lo g_{2} (4 - x) = 2

lo g_{3} (4 x + 8) - 7 = - 3

(ln (x) + 1) = 0

20 - ln (3 - x) = 0
