solvefor x,5ln(4x+4)+4=-11

solve for

x, 5 ln (4 x + 4) + 4 = - 11

x = \frac{1 - 4 e ^{3}}{4 e ^{3}}

Decimal Notation

x = - 0.98755 \dots

Solution steps

5 ln (4 x + 4) + 4 = - 11

Move

4

to the right side

5 ln (4 x + 4) = - 15

Divide both sides by

5

ln (4 x + 4) = - 3

Apply log rules

4 x + 4 = \frac{1}{e ^{3}}

Solve

4 x + 4 = \frac{1}{e ^{3}} : x = \frac{1 - 4 e ^{3}}{4 e ^{3}}

x = \frac{1 - 4 e ^{3}}{4 e ^{3}}

Verify Solutions:

x = \frac{1 - 4 e ^{3}}{4 e ^{3}}

True

The solution is

x = \frac{1 - 4 e ^{3}}{4 e ^{3}}

1 = lo g_{b} (3)

y, x = - ln (y - 2)

ln (x + 2) - ln (x - 1) = 1

lo g_{10} (x) = 4.8

86.89 = 20 ln (x) + x
