Express your answer as both an exact expression and a decima

Express your answer as both an exact expression and a decimal approximation rounded to two decimal places. e=2.71828182845905

e3x-7=803x+9

Solution

e3x-7=803x+9

Take natural log on both sides:

ln(e3x-7) = (3x -9)ln80

3x -7 = (3x-9)ln80

3x(1 -ln80) = 7 -9ln80

x = ( 7 -9ln80)/( 1- ln80)

= -32.438/-3.382026

= 9.59129

x = 9.59
