$\frac{25- 7^x}{\cos\left(\frac{\pi }{8}\right)}=\frac{9}{5}$
Learn how to solve problems step by step online. Solve the equation (5^2-7^x)/cos(pi/8)=9/5. Calculate the power 5^2. Apply fraction cross-multiplication. Divide both sides of the equation by 5. We need to isolate the dependent variable x, we can do that by simultaneously subtracting 25 from both sides of the equation.
