Factor them
45=3*3*5
18=2*3*3
lcf=2*3*3*5=90
The another way to represent the same line, for solving
will be: 
<u><em>Explanation</em></u>
Given equation of the line is: 
"Solving
" means <u>we need to get</u>
<u>alone in left side.</u> So, we will eliminate all other terms except
from the left side.
First we will <u>subtract 2x </u>from both sides. So, we will get......

Now, we will <u>divide both sides by 3</u> for getting
alone. So.....

Thus, the another way to represent the same line, for solving
will be: 
We are given dimensions of model and actual figure.
model: 9.5cm actual : 30.5m.
We need to find the length of actual shape for the scale factor 5cm.
Let us assume actual length be x m.
Let us set a proportion now.
<h3>5 : x = 9.5 : 30.5</h3>
Let us convert proportion into fractions.

On cross multiplying, we get
9.5x = 5× 30.5
9.5x = 152.5.
On dividing both sides by 9.5, we get

x=16.05.
<h3>Therefore, the scale factor for a model is 5cm= 16.05 m.</h3>
Answer:
Move all terms that don't contain x to the right side and solve.
x = −2
