Answer 2

It looks like you've provided three equations. Let's solve them one by one:

1. $2(x+3) = 6.5+x$

First, distribute the 2 on the left side:

$2x + 6 = 6.5 + x$

Now, let's isolate x by moving the x term on the right side to the left side:

$2x - x = 6.5 - 6$

$x = 0.5$

So, the solution for the first equation is $x = 0.5$.

2. $4.6(y-3) = 4.2+y$

Again, distribute the 4.6 on the left side:

$4.6y - 13.8 = 4.2 + y$

Now, isolate y by moving the y term on the right side to the left side:

$4.6y - y = 4.2 + 13.8$

$3.6y = 18$

Now, divide both sides by 3.6 to find y:

$y = \frac{18}{3.6}$

$y = 5$

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

3. $x+3 = 5.7(x+10)$

First, distribute the 5.7 on the right side:

$x + 3 = 5.7x + 57$

Now, isolate x by moving the 5.7x term on the right side to the left side:

$x - 5.7x = 57 - 3$

$-4.7x = 54$

Now, divide both sides by -4.7 to find x:

$x = \frac{54}{-4.7}$

$x \approx -11.49$

So, the solution for the third equation is $x \approx -11.49$.
