A. 5(x - 2) = 2x + 1
B. 5(x - 2) = 2(x + 1)
C. 5x - 2 = 2x + 1
D. 2 - 5x = 1 + 2x
E. 5x + 1 = 2x - 2

Answer 1

C. 5x-2=2x+1

Explanation:

Let x be the number. We can use this to set up an equation:

5x-2=2x+1

We can write this by using key words such as "is" which refers to equals/is equivalent.
