Did They Just Come Up With EXP/LOG Killer Problem? [Korean CSAT 2026]

South Korean College Scholastic Ability Test (CSAT) is the test that South Korean high school seniors take in order to apply for the college.

This problem from CSAT 2026 (for students who start their college in 2026) is about graphs of exponential and logarithmic functions, and is indeed an interesting one. Many of you might successfully set up the equations using the conditions given in the problem. However, the resulting system of equations are nonlinear and so complicated that it cannot be solved by "standard" methods. So, can you find the way?
