Can I get some help on these please

<h2>Ex 5</h2>

Simply multiply the equation by 6, in order to get rid of the denominators:

\dfrac{x}{2}+\dfrac{y}{3} = 4 \iff 3x+2y=24

<h2>Ex 6</h2>

We have to rearrange the equation in the form

(x-x_0)^2+(y-y_0)^2=r^2

So that r is the radius, and 2r will be the diamater. We have to complete the squares: rewrite the equation as

x^2-6x+y^2+8y=144

You can see that x^2-6x is the beginning of x^2-6x+9 = (x-3)^2

Similarly,  y^2+8y is the beginning of y^2+8y+16 = (y+4)^2

So, if we add 16 and 9 to both sides, the equation becomes

x^2-6x+9+y^2+8y+16=144+9+16 \iff (x-3)^2+(y+4)^2=169

So, now we know that r^2=169, and thus the radius is 13, so the diameter is 26.
