Question

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

Answer 1

Answer: 5

Solution,

5x+23=-2x-12
or, 5x+23+2x=-12
or, 5x+2x=-12-23
or, 7x=35
or, x=35/7
Therefore, x=5

Answer 2

x = - 5

Explanation:

5x + 23 = - 2x - 12 ( add 2x to both sides )

7x + 23 = - 12 ( subtract 23 from both sides )

7x = - 35 ( divide both sides by 7 )

x = - 5
