You must separate the variable x to one side, and the same with the integers.
x+5=4x-10
subtract x from both sides:
5=3x-10
Add 10 to both sides:
15=3x
Divide each side by 3:
5=x
x=5
Ans=E
x+5=4x-10
subtract x from both sides:
5=3x-10
Add 10 to both sides:
15=3x
Divide each side by 3:
5=x
x=5
Ans=E
