<em> 2x = 18 - y</em> is a perfectly good equation just as it stands.
If you were considering representing the equation as a graph, then
you might want to rearrange it, into a form that immediately reveals
some characteristics of the graph. That would make your job easier.
You'd want to rearrange it into 'standard' form for graphing, with 'y' on
one side of the equation and everything else on the other side, like this:
<em> </em> <u>2x = 18 - y</u>
Add 'y' to each side: y + 2x = 18
Subtract 2x from each side: y = -2x + 18
In this form, the equation shows that when it's graphed, the slope
of the line will be -2, and the line will cross the y-axis at the point
where y=18 .

This is because in order to attain the ratio 1:2 the reds have to be half the blues
Step 2 and all that follows is wrong because it should equal 20

<em><u>Question:</u></em>
Geoffrey is evaluating the expression (-3)^3(2^6)/(-3)^5(2^2) as shown below.
(-3)^3(2^6)/(-3)^5(2^2) = (2)^a/(-3)^b = c/d
What are the values of a, b, c, and d?
<em><u>Answer:</u></em>
<em><u>The values are a = 4, b = 2, c = 16, d = 9</u></em>
<em><u>Solution:</u></em>
Given that,
Geoffrey is evaluating the expression
He is evaluating as shown below:
From given,
Use the law of exponent
Therefore,
Thus,
a = 4
b = 2
Simplify further
Thus,
c = 16
d = 9
Thus values are a = 4, b = 2, c = 16, d = 9
