Answer 3

You have provided two equations, and it looks like you're interested in solving them for the variable x. Let's solve each equation step by step:

1. $6x - 8 = 4x + 6$

First, let's simplify the equation by subtracting $4x$ from both sides:

$6x - 4x - 8 = 6$

$2x - 8 = 6$

Now, add 8 to both sides to isolate $2x$:

$2x - 8 + 8 = 6 + 8$

$2x = 14$

Finally, divide both sides by 2 to solve for $x$:

$x = \frac{14}{2}$

$x = 7$

So, the solution for the first equation is $x = 7$.

2. $7(x - 3) = x + 9$

First, distribute the 7 on the left side of the equation:

$7x - 21 = x + 9$

Now, subtract $x$ from both sides:

$7x - x - 21 = 9$

$6x - 21 = 9$

Next, add 21 to both sides:

$6x - 21 + 21 = 9 + 21$

$6x = 30$

Finally, divide both sides by 6 to solve for $x$:

$x = \frac{30}{6}$

$x = 5$

So, the solution for the second equation is $x = 5$.

To summarize:

1. $x = 7$
2. $x = 5$
