To answer this question, we need to sum like terms in each case to solve for x. We can proceed as follows:
1. Subtract x to both sides of the equation:
[tex]5x-x+10=x-x+30\Rightarrow4x+10=30[/tex]2. Subtract 10 from both sides of the equation:
[tex]4x+10-10=30-10\Rightarrow4x=20[/tex]3. Divide by 4 to both sides of the equation:
