Помогите решить все вот эти примеры: 1)21(18+Х)=714. 2)16(4х-34)=608 3)12(152+19х)=2052 4)(152+32)*6=192 5)14х+4х-48=240

1) 21(18+Х)=71418 + x = 714/2118 + x = 34x = 34 – 18 = 162) 16(4x – 34) = 6084x – 34 = 608/164x – 34 = 384x = 38/344x = 19/17x = 19/(17*4) = 19/683) 12(152 + 19x) = 2052152 +19x = 2052/12152 + 19x = 17119x = 171-15219x = 19x = 14) (152+32x)*6 = 192152+32x = 192/6152 + 32x = 3232x = 32-15232x = -120x = -120/32x = -15/4 = - 3 3/45) 14x +4x – 48 = 24018x = 240+4818x = 288x = 288/18x = 166) 25x-7x-9=279 (25 – 7)x = 279+918x = 288x = 16Ответ: 1) x = 16; 2) x = 19/68; 3) x = 1; 4) -3 3/4; 5) x = 16; 6) x = 16
