Answer:
The most obvious one i can think of would be
x = 13
Step-by-step explanation:
x + 8 = 21
x + 8-8 = 21-8
x = 13
The value of the "x" will be "13".
The given equation is:
→ [tex]x+8=21[/tex]
By subtracting "8" from both sides of the equation, we get
→ [tex]x+8-8=21-8[/tex]
By applying the subtraction, we get
→ [tex]x = 13[/tex]
Thus the above answer is correct.
