1) (y+467)-775=0 2) (738+114)-(514+y)=0 1) 250-(105-(36+a))=245 2) (127-y)÷4=24 3) (y-117)×11=121

1) (y + 467) - 775 = 0.y + 467 - 775 = 0.y = 775 - 467.y = 308.2) (738 + 114) - (514 + y) = 0.738 + 114 - 514 - y = 0.y = 738 + 114 - 514.y = 338.3) 250 - (105 - (36 + a)) = 245.250 - (105 - 36 - a) = 245.250 - 105 + 36 + a = 245.a = 245 - 250 + 105 - 36.a = 64.4) (127 - y) / 4 = 24. | * 4127 - y = 96.y = 127 - 96.y = 31.5) (y - 117) * 11 = 121. | : 11y - 117 = 11.y = 11 + 117.y = 128.Ответ: 1) y = 308; 2) y = 338; 3) a = 64; 4) y = 31; 5) y = 128.
