SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the given expression
[tex]3x+6=3x-4[/tex]STEP 2: Simplify the expression
Subtract 3x from both sides
[tex]\begin{gathered} 3x+6-3x=3x-4-3x \\ 0+6=-4+0 \\ 6=-4 \end{gathered}[/tex]No solution: This type of equation is never true, no matter what we replace the variable with.
