Question

Given the equation 5x + 23 = − 2x − 12, which order of operations completely solves for x?

Answer 1

Option D, Subtract 5x, add 12, divide by -7

Explanation:

5x+23= -2x-12

subtract 5x from both sides to get

23 = -7x - 12

add 12 to both sides to get

35 = -7x

divide both sides by -7

x = -5

Answer 2

5x + 23 = -2x - 12
First, you carry the variables to one side and the rational numbers to the other.
5x + 23 = -2x - 12
- 23 = +23
________________
5x = -2x + 11
+2x = +2x
________________
7x = 11
The you divide 11 by 7 to get x.
x = 1.571

Hope this helps!
