Answer 2

It looks like you've provided three different equations. Do you need help solving these equations for their respective variables? If so, I can certainly assist you with that. Let's solve each equation step by step:

1. $2x + 13 = 77$: Subtract 13 from both sides to isolate the term with the variable. $2x = 77 - 13$ $2x = 64$ Divide both sides by 2 to solve for $x$. $x = \frac{64}{2}$ $x = 32$

2. $6x + x + 2x = 117$: Combine like terms on the left side of the equation. $9x = 117$ Divide both sides by 9 to solve for $x$. $x = \frac{117}{9}$ $x = 13$

3. $15 + 3x = 30$: Subtract 15 from both sides. $3x = 30 - 15$ $3x = 15$ Divide both sides by 3 to solve for $x$. $x = \frac{15}{3}$ $x = 5$

So, the solutions for the equations are:

1. $x = 32$
2. $x = 13$
3. $x = 5$
