The equation would just be x=8 since the x of both points is 8.
The answer is W>33 this is as simplified at it can be
Just multiply the with and the length by four (considering the scale factor is 4)
3x4=12 and 7x4=28
First we must change these numbers to improper fractions:


So then we set it up:
÷ 
When we divide fractions like this, we must flip the second fraction and change the sign from division to multiplication like so:

Then we solve:

Then if we divide the numerator and the denominator by 9, we get:
or, in mixed-number form,
.
