Answer: 20.25ft
1. Find what 8 inches in scale equal for the height of the house.
we will do this step by multiplying.
2in=4.5
8=?
to find...
2x4=8
so
4.5x4=18
2. Find what 1 inch on the scale is equal to for the height of the house.
we will do this by dividing 4.5 by 2
4.5/2=2.25
3. Add both the values for step 1 and 2.
we will do this by just adding them both
18+2.25=20.25
<h2>Why is this our answer?</h2>
This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!
My gratitude attitude - THANKS!

Step-by-step explanation:
We have to get one positive 7y so,
4x-7y=5
9x-7y=-15
multiply anyone of the equation by -1. I choose the first one so,
4x+7y=-5
9x-7y=-15
we can now cancel the y's so the equation will be left with
-4x=-5
9x=-15
add the equations
5x=-20
divide by 5 n u get
x=-4
now plug in the x value in any one of the
equations
I choose the first one so,
4(-4)-7y=5
-16-7y=5
add 16 to both sides
-7y=21
divide by -7
y=-3.
finally check.
