Tick nhé
219-7(x+1)=100
212(x+1)=100
x+1=100:212
x+1=2,12
x=2,12-1
x=1,12
Câu hỏi tương tự Đọc thêm219 - 7( x + 1 ) = 100
7 ( x + 1 ) = 219 - 100 = 119
x + 1 = 119 : 7 = 17
x = 17 - 1
x = 16
Vậy x = 16.
219 +7.x+1=100
⇔7x=100-219-1
⇔7x=-120
⇔x=\(\frac{-120}{7}\)
219 +7 . x + 1 = 100
(219 + 1) + 7. x = 100
220 + 7. x = 100
7 . x = 100 - 220
7 . x = -120
x = (-120) : 7
x = \(\frac{-120}{7}\)
219-7.(x+1)=100
=> 7.(x+1)=219-100
=> 7.(x+1)=119
=> x+1=17
=> 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
tik mik nha!
219 - 7 . (x + 1) = 100
\(\Rightarrow\) 7 . (x + 1) = 219 - 100
\(\Rightarrow\) 7 . (x + 1) = 119
\(\Rightarrow\) x + 1 = 119 : 7
\(219-7.\left(x+1\right)=100\)
\(7.\left(x+1\right)=219-100\)
\(7.\left(x+1\right)=119\)
\(\left(x+1\right)=119:7\)
\(\left(x+1\right)=17\)
\(x=17-1\)
\(x=16\)
Vậy \(x=16\)

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
kick di
\(219-7\left(x+1\right)=100\)
\(7\left(x+1\right)=219-100\)
\(7\left(x+1\right)=119\)
\(x+1=119\div7\)
\(x+1=17\)
\(x=17-1\)
\(x=16\)
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.
