Question

35 x 5 - 54 : m x 4=139
m : 2 + 45 - 25 : (36-99:9) =73
(a : 5 +105) : 100 =3
plssss​

Answer 1

Răspuns:

Explicație pas cu pas:

$\bf 35 \cdot5 - 54 : m \cdot 4=139$

$\bf 175 - 54 : m \cdot 4=139$

$\bf 175 = 139 + 54 : m \cdot 4$

$\bf 175 -139 = 54 : m \cdot 4$

$\bf 36 = 54 : m \cdot 4~~~~\bigg|:4$

$\bf 9 = 54 : m$

$\bf m = 54 : 9$

$\bf \pink{\underline{m = 6}}$

$\bf m : 2 + 45 -25 : (36-99:9) =73$

$\bf m : 2 + 45 -25 : (36-11) =73$

$\bf m : 2 + 45 -25 : 25 =73$

$\bf m : 2 + 45 -1 =73$

$\bf m : 2 =73-45 +1$

$\bf m : 2 =29~~~\bigg|\cdot2$

$\bf \purple{\underline{~m =58~}}$

$\bf (a : 5 +105) : 100 =3~~~\bigg|\cdot 100$

$\bf a : 5 +105 =300$

$\bf a : 5 =300-105$

$\bf a : 5 =195~~~\bigg|\cdot5$

$\bf \red{\underline{~a=975~}}$

Bafta multa !
