✔ 最佳答案
well..it goes like this..2x + 3 ( 4 - x ) = 3x + 2
2x + 12 - 3x = 3x + 2
12 - 2 = 3x + 3x - 2x
10 = 4x
x = 10 / 4
x = 5 / 2
so the answer would be (B) x = 5 / 2
hope it was of some help!!..all the best! =0)

2x + 3(4 - x) = 3x + 2
2x + 12 - 3x = 3x + 2
-x + 12 = 3x + 2
12 = 4x + 2
10 = 4x
x = 10/4 or reduced: 5/2

accordig to my calculations it is 2.5
look,
2x + 12-3x= 3x +2
2x - 3x - 3x = 2 - 12
-4x = -10
x= 2.5
isnt it????

2x + 3(4 - x) = 3x + 2
2x+12-3x=3x+2
12-x=3x+2
12-2=3x+x
10=4x
x=10/4
x=5/2 answer//
Answer is B. x=5/2
2x+12-3x=3x+2
12-x=3x+2
12-2=3x+x
10=4x
x=10/4
x=5/2 answer//
Answer is B. x=5/2

2x + 3(4 - x) = 3x + 2
2x + 12 - 3x = 3x + 2
4 x = 10
x = 5/2
B
2x + 12 - 3x = 3x + 2
4 x = 10
x = 5/2

2x + 3(4 - x) = 3x + 2
2x + 12 - 3x = 3x + 2
2x - 3x - 3x = -12 + 2
-4x = -10
x = -10/-4
x = 5/2 (2.5)
(answer B)
2x + 12 - 3x = 3x + 2
2x - 3x - 3x = -12 + 2
-4x = -10
x = -10/-4
x = 5/2 (2.5)
(answer B)
