Question 15364
2(x+5)= x-12
2x + 10 = x-12


Subtract x from each side:
2x -x + 10 = x-x - 12
x+10 = -12


Subtract 10 from each side:
x+10-10= -12-10
x= -22


Check:  Follow the instructions of the problem.

Increase the number by 5, which would be -17, then double this would give you -34.


Decrease the same number -22 by 12 also gives you -34.
It checks!!
