Question

Which number(s) from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, if any, will solve this equation?

2x + 3 = 5x - 3

A) {2}

B) {1, 2}

C) {2, 3, 5}

D) none of them

Answer 1

Answer: A. {2}

Explanation:

Answer 2

We are given that:
2x + 3 = 5x - 3

We will solve the given to get the value of x as follows:
2x + 3 = 5x - 3
3 + 3 = 5x - 2x
6 = 3x
x = 6/3
x = 2

Now, we will check te given set to see if 2 belongs to the set or not. We will find that 2 is an element in the given set.

Therefore, the correct choice is:
A) {2}

hope this helps :)
