-8x - 60 = -164

Add 60 to both sides, because whatever you do on one side, you have to do it to the other side

-8x = -104

Divide -8 to both sides

x = 13

Answer and Explanation:

You got the first one right!

2. You do the same as you did for the first one: to combine the exponents, you multiple 2 by 9 = 18, and now 18 is your new exponent.

$3^{2*9} = 3^{18}$ , which is the answer

3. Here, you can split up the inside so that you have:

$2^5*(y^2)^5= 32*y^{2*5}=32y^{10}$ , which is the answer

Hope this helps! Please give me brainliest if possible.
