Answer:
![-5\:\mathrm{and}\: 11](https://tex.z-dn.net/?f=-5%5C%3A%5Cmathrm%7Band%7D%5C%3A%2011)
Step-by-step explanation:
We can write the following system of equations:
![\begin{cases}x+y=6\\x-y=16\\\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7Dx%2By%3D6%5C%5Cx-y%3D16%5C%5C%5Cend%7Bcases%7D)
Adding both equations together, we isolate
and get:
![2x=22,\: x=11](https://tex.z-dn.net/?f=2x%3D22%2C%5C%3A%20x%3D11)
Plugging
in any of the equations, we can solve for
:
![11+y=6,\: y=-5](https://tex.z-dn.net/?f=11%2By%3D6%2C%5C%3A%20y%3D-5)
Verify that the solution pair
works ![\checkmark](https://tex.z-dn.net/?f=%5Ccheckmark)
Therefore, the two numbers are
.
The values of x are -22 and -2 and there are not extraneous solutions
<h3>How to solve the equation?</h3>
The equation is given as:
2|x + 7|= x - 8
Expand the absolute bracket
|2x + 14|= x - 8
Remove the absolute bracket
2x + 14 = x - 8 and 2x + 14 = -x + 8
Evaluate the like terms
x = -22 and 3x = -6
This gives
x = -22 and x = -2
Hence, the values of x are -22 and -2 and there are not extraneous solutions
