1). Решить уравнение: 1) 29х-15х+16=100; 2) 11у+32у-127=45; 3) 15z+8z-59=102; 4) 9t+4t-286=0; 5) 14x+9x+88=272; 6) 25x-16x+54=162.

Решение: * 29х - 15х + 16 = 100;29х - 15х = 100 – 16;14х = 84;х = 84 / 14;х = 6. * 11у +32у -127 = 45;11у +32 у = 45 + 127;43у = 172;у = 172 / 43;у = 4. * 15z + 8z -59 = 102;15z + 8z = 102+59;23z = 161;z = 161 / 23;z = 7. * 9t + 4t - 286 = 0;9t + 4t = 286;13t = 286;t = 286 / 13;t = 22. * 14x + 9x + 88 = 272;14x + 9x = 272 - 88;23x = 184;х = 184 / 23;х = 8. * 25x - 16x + 54 = 162;25x - 16x = 162 - 54;9x = 108;х = 108 / 9;х = 12.Ответ: 1) х = 6; 2) у = 4; 3) z = 7; 4) t = 22; 5) х = 8; 6) х = 12.
