Answer:

x = -3

Step-by-step explanation:

The LCD is 6, so multiply both sides by 6.

6[(3x + 1)/2] - 6[(4x - 3)/3] = 6 * 1

3(3x + 1) - 2(4x - 3) = 6

9x + 3 - 8x + 6 = 6

x + 9 = 6

x = -3

Solving Exponential Equations (lacking a common base)<br> 31^d=38
Bond [772]

Answer:

d = log 38/log31

d = 1.06

Step-by-step explanation:

31 ^ d = 38

Take log of both sides since the exponential equation have different base (always)

d log 31 = log 38

d = log 38 / log 31

d = 1.58 / 1.491

d = 1.06.

We can actually check to see if this is correct.

Substituting d = 1.06

31^ 1.06 = 38.092

(You see, that's approximately correct)
