✔ 最佳答案
First, subtract 3x from both sides. This leaves you with 25=5+5x. Then, subtract 5 from both sides. This results in 20=5x. Divide by 5 on each side and you get the answer x= 4 (or 4=x, either way). Hope this helps :)

25+3x=5+8x
25-5=8x-3x
20=5x
20/5=x
x=4
25-5=8x-3x
20=5x
20/5=x
x=4

add [ - 3 x - 5 ] to both sides ; then divide by the coefficient of x.....{ 4 }

3x + 25 = 8x + 5
- 5x = - 20
x = 4.
- 5x = - 20
x = 4.
