how do i solve for x. do i use the ln methode because i don't know how to do that. by calculator, i got x=.168 but i don't know how to show my work. please help me solve for x.

Take natural logs of both sides.

ln 2 + 4 x^2 = ln 3

4 x^2 = ln (3/2) = 0.40547

x^2 = 0.10137

x = (+ or -) 0.31838...

5x-12=2x-21
