Answer:
No answer as written. 16 if we add an equals sign.
Step-by-step explanation:
As written, there is no "=" sign in either expression. That means they are only expressions, not equations. x can be anything. 10, 12345, 0.00000343345567788, etc. There is nothing that restricts the value of x.
If we set the two expressions equal to each other, we can calculate a value of x:
(2x + 30) = (5x - 18)
3x = 48
x = 16
