7 (x+1) =219-100
7 (x+1) =119
x+1 = 119: 7
x+1 = 17
x =17-1
x =16
219 - 7 ( x + 1 ) = 100
7 ( x + 1 ) = 219 - 100
7 ( x + 1 ) = 119
x + 1 = 119 : 7
x + 1 = 17
x = 17 - 1
x = 16
219-7(x+1)=100
7(x+1)=219-100
7(x+1)=119
x+1=119:7
x+1=17
x=17-1
x=16
k mink nhé cấc bn
219 - 7 ( x + 1 ) = 100
<=> 7 ( x + 1 ) = 219 - 100 = 119
<=> x + 1 = 119 : 7 = 17
<=> x = 17 - 1 = 16
Vậy x = 16
219-7(x+1)=100
7(x+1)=219-100
7x+7 =119
7x =119-7
7x =112
x=112:7
x=16
219-7(x+1)=100
7(x+1)=219-100
7(x+1)=119
X+1=119:7
X+1=17
X=17-1
X = 16
219 - 7 ( x + 1) = 100
7 ( x + 1) = 219 - 100
7 ( x + 1 ) = 119
x + 1 = 119 : 7
x + 1 = 17
=> x = 17 - 1
=> x = 16
k đúng cho mk nha mk hứa sẽ k lại ^.-
7 . ( x + 1 ) = 219 - 100
7.( x +1 ) = 119
x + 1 = 119 : 7
x + 1 = 17
x = 17 -1
x = 16
vậy x = 16
219-7(x+1)=100
7(x+1)=219-100
7(x+1)=119
x+1=119:7
x+1=17
x=17-1
x=16
Vậy x=16
\(219-7\left(x+1\right)=100\)
\(7\left(x+1\right)=219-100\)
\(7\left(x+1\right)=119\)
\(x+1=119\div7\)
\(x+1=17\)
\(x=17-1\)
\(x=16\)
219 – 7(x + 1) = 100
7(x + 1) = 219 – 100
7(x + 1) = 119
x + 1 = 119 : 7
x + 1 = 17
x = 17 – 1
x = 16.
Vậy x = 16.
