Answer: the correct option is
(C)
Step-by-step explanation: Given that five times a number is the same as 30 more than 8 times the number.
We are to find the number.
Also, if the number is denoted by n, then we are to select the equation that could be used to solve for the number.
Since n is the given number, so five times the number is written as
Also, 30 more than eight times the number is written as
Since both the expressions are same, so we get
Thus, the required number is -10 and the the equation that is used to solve for the number is
Option (C) is CORRECT.

4x + 10 = 5x - 20
-x + 10 = -20 (Subtraction property of equality)
-x = -30 (Subtraction property of equality)
x = 30 (Division property of equality)
To check our work:
4(30)+10 = 130
5(30)-20 = 130
So, the value of x is 30!
