Question

11 - (x+48) = 97

-(x+48) + 213 = -16

tìm x

Answer 1

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____

Answer 2

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

Answer 3

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

Answer 4

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.

Answer 5

11 - (x + 48) = 97

=> x + 48 = 11 - 97

=> x + 48 = -86

=> x = -86 - 48

=> x = -134

Vậy x = -134

-(x + 48) + 213 = -16

=> -(x + 48) = -16 - 213

=> -(x + 48) = -229

=> x + 48 = 229

=> x = 229 - 48

=> x = 181

Vậy x = 181
