✔ 最佳答案
x+8= 2(2x-4)
multipy out the bracket to get
x+8= 4x-8
now gather the x terms on the left and the free terms on the right
x-4x=-8-8
-3x=-16
x=16/3
參考: Any kid over 12 should tell you, or if you can't find a kid over 12 find a first course book on algebra.

x + 8 = 4x - 8
16 = 3x
x = 16/3
x = 5⅓

x+8=2(2x-4)
x+8=2*x2+2*(-4)
x+8=4x-8
x+8-x+8=4x-8-x+8
8+8=4x-x
16=3x
x=16/3=5 1/3

x + 8 = 2(2x - 4)
x + 8 = 2*2x - 2*4
x + 8 = 4x - 8
x - 4x = -8 - 8
-3x = -16
x = -16/-3
x = 5 1/3
