ajudaaaaaaaa!!!!!!!!!​

Answer 1

Explicação passo-a-passo:

A= 872-827=45

$X+827=872\\X=827-872\\X=-45*(-1\\X=45$

B= 726-373=353

$X-726=373\\X=373-726\\X=-353*(-1\\X=353$

C= 372/3=124

$3*X=372\\X=372/3\\X=124$

D= 34/5=6.8

$5*X=34\\X=34/5\\X=6,8$

E= 118-52=66

$X=52+66\\X=118$

F= 513-402=111

$X+402=513\\X=513-402\\X=111$

G= 466/2=233

$2*X=466\\X=466/2\\X=233$

H= 37-23=14

$X+23=37\\X=37-23\\X=14$

I= 62-16= -42 multiplica por (-1) =46

$X-62=16\\X=62-16\\X=46$

J= 32/3= 10.666.....

$X*3=32\\X=32/3\\X=10.666.....$
