Hi! Your answer is x = 3.
Please see an explanation for a clear and better understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Our goal is to find the value of x. That means what we have to do is to isolate x-term first.
[tex]\huge{x+10=13}[/tex]
To isolate a variable means that to make a variable as a subject or also known as leaving a variable alone. To isolate the x-term for this problem, simply subtract both sides by 10 so we can get rid of 10 from the left side.
[tex]\huge{x+10-10=13-10}\\\huge{x+0=3}\\\huge{x=3}[/tex]
If you are not sure that the answer is correct or not. We can substitute the value of x in the equation.
[tex]\huge{x+10=13}[/tex]
Substitute x = 3 in the equation.
[tex]\huge{3+10=13}\\\huge{13=13}[/tex]
The equation is true for x = 3. Hence, we can conclude that x = 3 is the solution to the equation.
