Question

(45p-p):28=11, 324:(17p+p)=3, (105-n)*9=756, (y+25)*7=322, 221:(y-9)=17, 34*(x-8)=408 ПОМОГИТЕ РЕШИТЬ ПОЖАЛУЙСТА!!!

Answer 1

(45р-р):28 = 11
44р = 11*28
44р = 308
р = 308 : 44 = 7
324 : (17р+р) = 3
324 = 3 * 18р
54р = 324
р = 324 : 54 = 6
(105-n) * 9 = 756

(105-n) * 9 = 756 105 -n = 756 : 9 105 - n = 84 n = 105 - 84 = 21 (y +25) * 7 = 322 y + 25 = 322 : 7 y + 25 = 46 y = 46 - 25 = 21 221 : (y -9) = 17 221 = 17 * (y - 9) 221 = 17y - 153 17y = 221+153 = 374 y = 374 : 17 = 22 34*(x-8) = 408 x -8 = 408 : 34 x - 8 = 12 x = 12 + 8 = 20
