=Y+574=57246:87
=Y+574=658
=Y=658-574
=Y=84

\(\left(y+574\right)\times8=57246\)

\(y+574=57246:8\)

\(y+574=\dfrac{28623}{4}\)

\(y=\dfrac{28623}{4}+574\)

\(y=\dfrac{30919}{4}\)

hữu nghĩa ơi!Đề bài là 87 nhé bạn

a: Ta có: \(\left(x+574\right)\cdot87=57246\)

\(\Leftrightarrow x+574=658\)

hay x=84

b: Ta có: 8x+17x=15675

nên 25x=15675

hay x=627

\(a,\left(x+574\right)\times87=57246\\ \Rightarrow x+574=57246:87\\ \Rightarrow x+574=658\\ \Rightarrow x=658-574\\ \Rightarrow x=87\\ b,x:68+685=784\\ \Rightarrow x:68=784-685\\ \Rightarrow x:68=99\\ \Rightarrow x=99\times68\\ \Rightarrow x=6732\)

\(\text{( x + 574 ) × 87 = 57246}\)

\(\left(x+574\right)=658\)

\(x=658-547\)

\(=111\)

\(\text{ b. x : 68 + 685 = 754}\)

\(x:68=754-685=69\)

\(x=69\times68\)

\(x=4692\)

rồi tui nên tin ai đây

a. x = 84       b. x = 4692

a) \(\left(x+574\right)\times87=57246\)

\(x+574=57246:87\)

\(x+574=658\)

\(x=658-574\)

\(x=84\)

b) \(1752:x\times69=10074\)

\(1752:x=10074:69\)

\(1752:x=146\)

\(x=1752:146\)

\(x=12\)

\(a.\) \(\left(x+574\right)\times87=57246\)

\(x+574=57246:87\)

\(x+574=658\)

\(x=658-574\)

\(x=84\)

\(b.\) \(1752:x\times69=10074\)

\(1752:x=10074:69\)

\(1752:x=146\)

\(x=1752:146\)

\(x=12\)

thay dấu nhân bằng chữ x dc ha?:)

a: =>x+574=658

hay x=84

b: =>x:68=69

hay x=4692

c: =>18x=15667

hay x=15667/18

x + 574 . 87 =57246 

x + 574        = 57246 : 87 

x + 574        = 658

x                  = 658 - 574

x                  = 84

( x + 574 ) * 87 = 57246

x + 574 = 57246 : 87

x + 574 = 658

x = 658 - 574

x = 84 

Vậy x = 84

x+574=57246:87

x+574=658

x=658-574

x=84

( x + 547 ) x 87 = 57246

x + 547             = 57246 : 87 

x + 547             = 658

x                       = 658 - 547

x                       = 111

Vậy x =111

x = 111

trl sẽ có like

Máy tính có dấu nhân mà

a: =>x+574=658

hay x=84

b: =>x:68=69

hay x=4692

c: =>18x=15667

hay x=15667/18
