Решите уравнения:
а) 5x + 6x = 2211
б) 23x + x - 10 = 38
в) 1457 / ( 7 + 8x) = 47
г) 1.5x - 0.2x + 1.4x = 291.6

a) 5x + 6x = 221111x = 2211x = 2211/11x = 201б) 23x + x - 10 = 3824x = 38 + 1024x = 48x = 48/24x = 2в) 1457 / ( 7 + 8x) = 471457 / ( 7 + 8x) = 47 / 147 ( 7 + 8x) = 1457329 + 376x = 1457376x = 1457 - 329376x = 1128x = 1128 / 376x = 3г) 1,5x - 0,2x + 1,4x = 291,61,3x + 1,4x = 291,62,7x = 291,6x = 291,6 ÷ 2,7x = 108

а) 5х+6х=221111х=2211х=201Ответ: 201б) 23х+х-10=3824х=38+1024х=48х=2Ответ: 2в) 1457/(7+8х)=477+8х=1457/477+8х=318х=31-78х=24х=3Ответ: 3г) 1,5х-0,2х+1,4х=291,62,7х=291,6х=108Ответ: 108
