Answer: w = 9
Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.
18 + 4w = 6w
4w + 18 = 6w
Now we subtract 18 from both sides.
When we simplify, we get that w = 9.

The information from the first equation gives you the information needed for the second. To solve the first equation you must rearrange the equation to isolate X. In order to do that you can first move the 3 to the other side of the equation by subtracting it from both sides (5x + 3 - 3 = 4 - 3) and then simplify that to (5x = 4 - 3) and further to (5x = 1). Then to move the 5 you must divide both sides by 5 so you get (5x/5 = 1/5) which can be simplified to (x = 1/5)
From this you can use the X value and input it into the second equation
Y = -3(1/5) and then solve for Y.

First one I believe. Its been a couple years since I’ve done this so im not 100% sure
The decimal representation of any number is a linear combination of powers of 10. In other words, given a number like 123.456, we can expand it as
for any 
, so the above is the same as
Similarly, we can write
Now it's a question of reducing the fraction as much as possible. We have 
so
I need the answers for help you
