Question

Решите уравнения. (720+е)*501=365730 5t+30-2t=42 36*(x-3)=10-2*(x+2)

Answer 1

(720+е)*501 = 365730

360720+501е= 365730

201е = 5010

е=10

 

5т+30-2т=42

3т = 12

т=4

 

36*(х-3)=10-2*(х+2)

36х-108 = 10-2х-4

38х = 114

х=3

Answer 2

720+е=365730/501
720+е=730
е=730-720
е=10

5t+30-2t=42
3t+30=42
3t=12
t=4

36(x-3)=10-2(x-2)
36x-108=8x+16
36x-108-8x-16=0

28x-124=0
28x=124
x=124/28
