a)
( x - 35 ) - 112 = 0
=> x - 35 = 0 + 112 = 112
=> x = 112 + 35 = 147
b)
124 + ( 118 - x ) = 27
=> 124 + 118 - x = 27
=> 242 - x = 27
=> x = 242 - 27 = 215
c)
156 - ( x + 61 ) = 82
=> 156 - x - 61 = 82
=> 95 - x = 82
=> x = 95 - 82 = 13

a. 468 : 3 + 61 x 4
=156 + 244 = 300
b. 35 x 12 + 65 x 12
= 12 x 100 = 1200

a, (x - 35)-120=0
x-35=120+0
x-35=120
x=120+35
x=155
b,156-(x+61)=82
x+61=156-82
x+61=74
x=74-61
x=13
c,124+(188-x)=217
188-x=217-124
188-x=93
x=188-93
x=95
a) ( x - 35 ) - 120 = 0
x - 35 = 0 + 120
x - 35 = 120
x = 120 + 35
x = 155
b) 156 - ( x + 61 ) = 82
x + 61 = 156- 82
x + 61 = 74
x = 74 - 61
x = 5
c) 124 + ( 188 - x ) = 217
188 - x = 217 - 124
188 - x = 93
x = 188 - 93
x = 95
K MK NHA BẠN, MK CHẮC ĐÚNG LUN ĐÓ NHA, THANK BẠN NHÌU
X + 35 = 61
X = 61 - 35
X = 26
Chúc bạn học tốt!
x + 35 = 61
