Question

ai nhanh thì mk tick cho nè

Tìm x : \(219-7\left(x+1\right)=100\)

Answer 1

219 - 7 ( x + 1 ) = 100

7 ( x + 1 ) = 219 - 100

7 ( x + 1 ) = 119

x + 1 = 119 : 7

x + 1 = 17

x = 16

Answer 2

7x+1=219-100

7x=112

x=16

Answer 3

\(219-7\left(x+1\right)=100\)

\(7\left(x+1\right)=219-100\)

\(7\left(x+1\right)=119\)

\(\left(x+1\right)=119\div7\)

\(\left(x+1\right)=17\)

\(x=17-1\)

\(=>x=16\)

Answer 4

7(x+1)=219-100

7(x+1)=119

 x+1=119:7

x+1=17

x=17-6

x=11
