[ 234705 – x – ( 97579 + 0.38x )] / [ x + ( 97579 + 0.38x )] = 40%( 137126 – 1.38x ) / ( 97579 + 1.38x ) = 0.4137126 – 1.38x = 39031.6 + 0.552x1.932x = 98094.4x = 98094.4 / 1.932 = 50773.498可以一步一步幫我解釋算法和順序嗎比如為什麼( 137126 – 1.38x ) / ( 97579 + 1.38x ) = 0.4要先0.4*1.38x和0.4*97579又為什麼137126 – 1.38x = 39031.6 + 0.552x裡面的1.38x會+0.552x變1.932x請個個程度是國中高中這種數學要從何種程度學
