Answer:

x = (ln(7) -1)/2

Explanation:

Take the natural log:

... 2x +1 = ln(7)

Subtract 1, then divide by 2:

... 2x = ln(7) -1

... x = (ln(7) -1)/2

Answer:

x = [ln7 -1]/2

Explanation:

e ^ (2x+1) = 7

Take the natural log on each side

ln (e ^ (2x+1)) = ln (7)

2x+1 = ln(7)

Subtract 1

2x+1-1 = ln(7)-1

2x= ln(7)-1

Divide by 2

2x/2 = (ln(7)-1))/2

x = [ln7 -1]/2
