Question

Как решить уравнения (720+e)*501=365730
и (r+2958):87=134

Answer 1

(720+e)*501=365730
720+е=365730:501
720+е=730
е=730-720
е=10

(r+2958):87=134
r+2958=134*87
r+2958=11658
r=11658-2958
r=8700

Answer 2

( 720+ е)* 501= 365730
720+е= 365730: 501
е= 730- 720
е= 10
( r+ 2958):87=134
r+2958= 134*87
r=11658-2958
r=8700
