Question

Solve.

A
x = 3

B
x = 18

C
x = 36

D
x = 72

Answer 1

x = 36

Explanation:

We are given the equation:

`\displaystyle \large{x + 18 = 54}`

Subtract 18 both sides to isolate x-term.

`\displaystyle \large{x + 18 - 18= 54 - 18} \\ \displaystyle \large{x = 36}`

And we're done! If you have any questions, let me know through comment.
