Solve the following equation for the exact value of x. If there is no solution, enter DNE. If there is just one solution, enter DNE for x2. If there are 2 solutions, enter the greater solution for x1.

ln(7x2+4)=ln(16x+17).

x1=

x2=

check my answer please:
x1=2.92141422
x2=-0.63569994

thank you

Looks good to me
although, if they want exact values, maybe you should put
(8+√155)/7
and
(8-√155)/7
