Question

3.(2.x+1)-19=14
Giúp mình nha mình đang cần gấp, mai mình thi Toán rồi.

Answer 1

\(3\left(2x+1\right)-19=14\)

\(3\left(2x+1\right)=33\)

\(2x+1=11\)

\(2x=10\)

\(x=5\)

Answer 2

3.(2.x+1)-19=14

3.(2.x+1)-19=14+19

3.(2.x+1)-19=33

(2.x+1) =33:3

(2.x+1) = 11

2.x =11-1

2.x = 10

x = 10:2

x = 5

Answer 3

3.(2.x+1)-19=14

3.(2.x+1)-19=14+19

3.(2.x+1)-19=33

(2.x+1) =33:3

(2.x+1) = 11

2.x =11-1

2.x = 10

x = 10:2

x = 5
