Question

Решите уравнение
x+57=62;
71-x=51;;
x-31=20;
82-x=70;
27+x=35;
x-300=500

Answer 1

1) x=62-57
x= 5
2) x= 71-51
x= 20
3) x= 20+31
x=51
4)x=82-70
x=12
5)x=35-27
x=8
6)x=500+300
x=800

Answer 2

X+57=62
x=62-57
x=5

71-x=51
-x=51-71
×=-20/-1
x=20

x-31=28
x=28+31
x=59

82-x=70
-x=70-82
-x=-12
x=-12/-1
x=12

27+x=35
x=35-27
x=8

x-300=500
x=500+300
x=800
