Substitute the given solution into the corresponding equation to check it. Then decide if the solution is correct or incorrect.  

1. $5x+8=3x-2$ 

   Hint (a):

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

   More Help (a):

   $\begin{array}{l} 5(-5)+8=3(-5)-2\\ \; \; \; -25+8=-15-2 \end{array}$

• Solution: $x=-5$ 

  Answer (a):

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

2. $2(x+1)+6=20-3x$ 

   Hint (b):

   See part (a).

• Solution: $x=4$
