Question

реши уравнение (720+е)•501=365730 5t+30-2t=42 36•(x-3)=10-2•(x+2)

Answer 1

(720 + e)×501 = 365730
364520 +501e=365730
501e= 365730 - 364520
501e =1210
E= 1210÷ 501
E = 2,42


5t+30-2t =42
5t-2х =42 -30
3t = 12
T = 12÷3
T = 4

36 ×( x - 3) =10 - 2 × (x +2)
36x - 108 = 10 - 2x - 4
36x +2x = 10-4+108
38 x = 114
X = 114 ÷ 38
X = 3
