I've put my working in a spoiler below so you can check your own too Spoiler: Take the logs (base 10 will keep it simpler) Use the law to separate the left hand side Take log(3) from both sides and then use the law which says Factor out x: Divide through to isolate x:
yeah i got it, xlog2+xlog3+log3=1 log3=0.4771 log2=0.3010 therefore 0.3010x+0.4771x+0.4771=1
