Answer:

y=5.79x

Step-by-step explanation:

What you'll first do it divide both sides by y

So, y/y =5.79x/y

so the answer for question 1 is going to be 5.79xy.

If this is from the textbook, use slader. it might help you better than me.

Now do the same thing for the second one.

Be safe guys!:)

Answer:

x=-3

Step-by-step explanation:

You need to delete the root by ^2. First you need to leave it alone

$\sqrt{x+7}-x=5\\\sqrt{x+7}=5-x\\(\sqrt{x+7} )^{2}=(5-x)^{2} \\x+7=25+10x+x^2\\x-10x=25+x^2-7\\-9x=18+x^2\\-x^2-9x-18=0\\-1(x^2+9x+18)=0\\x^2+9x+18=\frac{0}{-1}\\x^2+9x+18=0\\(x+6)(x+3)=0\\x+6=0 ===> x=-6\\x+3=0 ===> x=-3\\Checking\\\sqrt{-6+7}-(-6)=5===>\sqrt{1}+6=7\neq5 \\\\\sqrt{-3+7}-(-3)=5===>\sqrt{4}+3=5=5\\\\So \\x=-3$
