11 - (x+48) = 97
=> x + 48 = 97 - 11
=> x + 48 = 86
=> x = 86 - 48
=> x = 38
vậy____
-(x+48) + 213 = -16
=> -x - 48 = -16 - 213
=> -x - 48 = -229
=> -x = -229 + 28
=> -x = -201
=> x = 201
vậy____
1, 11-(x+48)=97
\(\Rightarrow x+48=11-97\)
\(\Rightarrow x+48=-86\)
\(\Rightarrow x+48=-134\)
Vậy x=134
2,-(x+48)+213=-16
\(\Rightarrow-\left(x+48\right)=-16-213\)
\(\Rightarrow-\left(x+48\right)=-229\)
\(\Rightarrow x+48=229\)
\(\Rightarrow x=229-48\)
\(\Rightarrow x=181\)
Vậy x=181
11 - (x+48) = 97
x + 48 = 11 - 97
x + 48 = - 86
x = - 86 - 48
x = - 134
-(x+48) + 213 = -16
- ( x + 48 ) = - 16 - 213
- ( x + 48 ) = - 229
- x - 48 = - 229
- x = - 229 + 48
- x = - 181
=> x = 181
a) 11-(x+48)=97
<=> x+48=11-97
<=> x+48=-86
<=> x=-86-48
<=> x=-134
b) -(x+48)+213=-16
<=> (-x)-48=(-16)-213
<=> (-x)-48=-229
<=> x+48=229
<=> x=229-48
<=> x=181
k mình nhé.
