Question

Reyna chose four numbers and created an equation with a solution of 2x. Which four digits did Reyna choose? Create an equation with those four digits that results in a solution of 2x.

A. 1, 2, 3, 4
B. 5, 6, 7, 8
C. 9, 0, 1, 2
D. 3, 5, 7, 9

Answer 1

The four digits that Reyna chose are 5, 6, 7, and 8. The equation that results in a solution of 2x is 5 + 6 + 7 - 8 = 2x.

Step-by-step explanation:

To find out which four digits Reyna chose, we need to create an equation with a solution of 2x. Let's use the four digits from option B: 5, 6, 7, and 8. The equation would be:

5 + 6 + 7 - 8 = 2x

Simplifying, we have:

x = (5 + 6 + 7 - 8) / 2 = 5

Therefore, the four digits that Reyna chose are 5, 6, 7, and 8. The equation that results in a solution of 2x is 5 + 6 + 7 - 8 = 2x.
