Hey there,
The answer is: 18a^3b2/2ab=9a^2*b

Hey there!
The main concept of pre-algebra is solving equations for variables in them.
For example, let's say you have the algebraic equation below.
x+1=3
With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.
We would subtract 1 to both sides to isolate x on one side.
x+1-1=3-1
As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.
x=3-1
x=2
Therefore, in our equation x+1=3, x would be equal to 2.
I hope this explanation helps! Have a great time here at Brainly!
From both sides of the equation, 4 should have been subtracted.
The solution should look like this:
X + 4 = 28
From each side, subtract 4 :
<em>X = 24</em>
I'd like to demonstrate more steps, but the answer has already popped up, so there aren't any more steps.
<em><u>Question:</u></em>
One dollar is worth 3 1/2 kruneros. What is the value of 43 3/4 kruneros?
<em><u>Answer:</u></em>
The value of 
kruneros is 12.5 dollars
<em><u>Solution:</u></em>
Given that,
Dollar is worth three and 3 1/2 kruneros
Which means,
We have to find the value of kruneros
Let us convert the mixed fractions to improper fractions
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator.
So we have to find the value of 43.75 kruneros
Let "x" be the value of 43.75 kruneros
Then,
1 dollar = 3.5 kruneros
x dollar = 43.75 kruneros
This forms a proportion and we can solve the sum by cross multiply
Thus value of kruneros is 12.5 dollars
