Question

(x - 35) - 120 = 0

124 + (118 - x) = 217

156 - (x + 61) = 82

Giúp mình ghi đầy đủ nha các bạn :)

Answer 1

(x - 35) - 120 = 0

<=> x-35-120=0

<=> x=155

124 + (118 - x) = 217

<=> 242-x=217

<=> x=25

156 - (x + 61) = 82

<=> 156-x-61=82

<=> 95-x=82

<=> x=13

Answer 2

a, (x - 35) - 120 = 0

=> x - 35 = 0 + 120

=> x - 35 = 120

=> x = 120 + 35

=> x = 155

b, 124 + (118 - x) = 217

=> 118 - x = 217 - 124

=> 118 - x = 93

=> x = 118 - 93

=> x = 25

c, 156 - (x + 61) = 82

=> x + 61 = 156 - 82

=> x + 61 = 74

=> x = 74 - 61

=> x = 13

Answer 3

a, \(\left(x-35\right)-120=0\)

\(x-35=120\)

\(x=155\)

b, \(124+\left(118-x\right)=217\)

\(118-x=93\)

\(x=25\)

c, \(156-\left(x+61\right)=82\)

\(x+61=74\)

\(x=13\)

Answer 4

(x - 35) - 120 = 0

=> x - 35 = 120

=> x = 120 + 35

=> x = 155

124 + (118 - x) = 217

=> 118 - x = 217 - 124

=> 118 - x = 93

=> x = 118 - 93 = 25

156 - (x + 61) = 82

=> x + 61 = 156 - 82

=>  x + 61 = 74

=> x = 74 - 61 = 13

Answer 5

\(c,\)\(156-\left(x+61\right)=82\)

\(\Rightarrow156-x-61=82\)

\(\Rightarrow156-61-82=x\)

\(\Rightarrow x=13\)
