✔ 最佳答案
2x + 5 = 9
2x + 5 - 5 = 9 - 5
2x = 4
2x/2 = 4/2
x = 2
2x + 5 = 9
2x + 5 - 5 = 9 - 5
2x = 4
2x/2 = 4/2
x = 2
All correct except you left out the + 5 in the second line.
Nope. Well, your answer is right, but you need to do the same to both sides, so in the second step you need to subtract 5 from both sides (not just drop the 5 from the left side). You had it very close.
2x +5 = 9
2x+5-5=9-5
2x=4
2x/2= 4/2
X=2
