Show the check for each of these problems and decide if the solution is correct or incorrect.

1. $5x + 8 = 3x-2$ Solution: $x =-5$

   Hint (a):

   Substitute the value in for $x$ and solve to see if the two sides are equal to each other.

   More Help (a):

   $5 (−5) + 8 = 3 (−5) −2$
   $−25 + 8 = −15 − 2$

   Answer (a):

   $−17 = −17$
   Solution $x =-5$ is correct.

2. $2(x + 1) + 6 = 20-3x$ Solution: $x = 4$

   Hint (b):

   See part (a).
