Step-by-step explanation:
x+4=15
subtract by 4 both sides of an equation.
x+4-4=15-4
then simplify.
15-4=11
x=11 is the final answer.
Hope this helps!
Thanks!
Have a great day!
x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
