If 9x+2 = 36, then 3x ?
回答 (5)
✔ 最佳答案
9x + 2 = 36
9x = 36 - 2
9x = 34
x = 34/9
3x = 3 x 34/9
3x = 34/3
9x + 2 = 36
9x / 3 + 2 / 3 = 12
3x = 12 - 2/3
3x = 12 - 0.666666666
3x = 11.3333333333333333
9x + 2 = 36
9x = 36 - 2
x = 34 / 9
x = 3.78

9 x (3.78) + 2 = 36.02and x = 3 7/9

3x = 3 x 3.78 or 3x = 3 x 3 7/93x = 11.34 or 3x = 11 3/9
參考: me
9x/3=3x
9x+2=36
9x=36-2
9x=34
3x=34/3
=11.33
9x=34
3x=34/3
3x=11.33333333
