✔ 最佳答案
4c+5=2c4c=2c-5
4c-2c=-5
2c=-5
c=5/-2
c=-2.5
4c+5=2c
將(+5)調去另一面變(-5)
再將(+2c)調去另一面變(-2c)
(4c-2c)等於(2c)
(2c)等於(-5)
將個(2)調去另一面變成5除以-2(5/-2)
所以c等於(-2.5)
希望我可以幫到你;D

No.1 4c+5 = 2c
No.2 2c = -5
No.3 c = -5 over 2 (-5 / 2)
No.4 c = -2.5
解說:
No.2 將2c 調過去左邊, +5調去右邊
= 4c-2c +5-5 = 2c-2c -5
= 4c-2c = -5
