Question

(x-1) + (x-2) + (x-3) = 180

Các Bạn Giari Giusp mình với ! Cảm ơn

Answer 1

( x - 1 ) + ( x - 2 ) + ( x - 3 ) = 180

x - 1 + x - 2 + x - 3 = 180

3x - 1 - 2 - 3 = 180

3x - ( 1 + 2 + 3 ) = 180

3x - 6 = 180

3x = 180 + 6

3x = 186

x = 186 : 3

x = 62

Answer 2

=>x-1+x-2+x-3=180

x3-6=180

3x=174

x=58

Answer 3

(x-1)+(x-2)+(x-3)=180

x-1+x-2+x-3=180

3.x -1-2-3 = 180

3.x - 6 = 180

3.x = 180 + 6

3.x = 186

x = 62

Answer 4

(x-1)+(x-2)+(x-3)=180

=>3x-1-2-3=180

=>3x        =180+3+2+1

=>3x        =186

=>x         =186:3

=>x         =62

Answer 5

bằng 62 hả bạn ??

Answer 6

x - 1 ) + ( x - 2 ) + ( x - 3 ) = 180

x - 1 + x - 2 + x - 3 = 180

3x - 1 - 2 - 3 = 180

3x - 6 = 180

3x = 180 + 6 

3x = 186

x = 186 ÷ 3 

x = 62

Answer 7

62 nhé 100% đúng
