Question

Реши уравнения.
(720+e)*501=365730
5t+30-2t=42
36*(x-3)=10-2*(x+2)
Помогите решить срочно!!!

Answer 1

720 + е = 365730 : 501
720 + е = 730
е = 730 - 720
е = 10
-------------------------
5t - 2t = 42 - 30
3t= 12
t = 4
-------------------
36x - 108 = 10 - 2x - 4
36x + 2x = 108 + 10 - 4
38x = 114
x = 3
