Tìm x: 156 - ( x + 61) = 82
Ai đúng t tick
124 + ( 118 - x ) = 217
156 - ( x + 61 ) = 82
Nhanh đúng mình tick , làm rồi mà không biết cách làm với kết quả có đúng không ~~
124 + ( 118 - x ) = 217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25
156 - ( x + 61 ) = 82
x + 61 = 156 - 82
x + 61 = 74
x = 74 - 61
x = 13
124 + (118 -x ) = 217 156 - ( x+61) = 82
(118-x) = 217 -124 ( x +61)= 156 - 82
(118 -x)= 93 ( x +61) = 74
x = 118 - 93 x = 74 - 61
x = 25 x = 13
124 + ( 118 - x ) = 217
124 + 118 - x = 217
- x = 217 - 124 - 118
- x = - 25
x = 25
156 - ( x + 61 ) = 82
156 - x - 61 = 82
- x = 82 + 61 - 156
- x = - 13
x = 13
Bài 3 : Tìm x, biết :
a, ( x - 140 ) : 35 = 270
b, ( x + 200 ) : 4 = 460 + 85 x 4
c, 7,2 : 2,4 x x = 4,5
d, 2448 : [ 119 - ( x - 6) ] = 24
e, 156 - ( x + 61 ) = 82
g, ( 5376 - x ) 3877 = 904
h, x - 4867 = ( 175 x 2 + 50 x 70) : 25 + 23
Ai nhanh và đúng mk tick cho 3 tick
a)(x-140):35=270
(x-140)=270:35=54/7
x=54/7+140=1034/7
Tìm số tự nhiên x, biết: 156 – (x + 61) = 82
156 – ( x + 61) = 82
x + 61 = 156 – 82
x + 61 = 74
x = 74 – 61
x = 13.
Tìm x:
