Question

X1.4.141. Afla x + y, stiind că:
(36:(30 - x) + 49) : 5 = 11 şi y : [(971 - 689): 6-42] = 9


VĂ ROG, AJUTAȚI-MĂ!!! REPEDE​

Answer 1

Explicație pas cu pas:

Buna !!

•[36:(30-x)+49]:5=11

•36:(30-x)+49=11×5

•36:(30-x)+49=55

•36:(30-x)=55-49

•36:(30-x)=6

•30-x=36:6

•30-x=6

•x=30-6

•x=24

•y:[(971-689):6-42]=9

•y:(282:6-42)=9

•y:(47-42)=9

•y:5=9

•y=9×5

•y=45

x+y=?

=>24+45=69 ✅

Succes !!;)

Answer 2

Salutare!:)

[36:(30-x)+49]:5=11

[36:(30-x)+49]=11×5

[36:(30-×)+49]=55

36:(30-×)=55-49

36:(30-×)=6

(30-x)=36:6

30-x=6

x=30-6

x=24

y:[(971-689):6-42]=9

y:(282:6-42)=9

y:(47-42)=9

y:5=9

y=9×5

y=45

x+y=24+45=69(suma)

Succes!
