Question

2x(4-3xX)+15=23

Answer 1

2.(4 - 3.x) + 15 = 23

2.(4 - 3.x) = 23 - 15

2.(4 - 3.x) = 8

4 - 3.x = 8 : 2

4 - 3.x = 4

3.x = 4 - 4

3.x = 0

x = 0 : 3

x = 0

Vậy x = 0

Answer 2

2x(4-3xX)+15=23

2x(4-3xX)=23-15=8

(4-3xX)=8:2=4

3xX=4-4=0

X=0:3=0

Đáp án: X=0

Answer 3

2x ( 4 - 3 . x ) + 15 = 23

2x ( 4 - 3 . x ) = 23 - 15

2x ( 4 - 3 . x ) = 8

( 4 - 3 . x ) = 8 : 2

4 - 3 . x = 4

3 . x = 4 - 4

3 . x = 0

=> x = 0 : 3

=> x = 0

Answer 4

2.(4 - 3.x) + 15 = 23

2.(4 - 3.x) = 23 - 15

2.(4 - 3.x) = 8

4 - 3.x = 8 : 2

4 - 3.x = 4

3.x = 4 - 4

3.x = 0

x = 0 : 3

x = 0

Vậy x = 0
