Answer:
x = 36
Step-by-step explanation:
We are given the equation:
[tex] \displaystyle \large{x + 18 = 54}[/tex]
Subtract 18 both sides to isolate x-term.
[tex] \displaystyle \large{x + 18 - 18= 54 - 18} \\ \displaystyle \large{x = 36}[/tex]
And we're done! If you have any questions, let me know through comment.
