1) 8y + 9 2) 2n + 4 3) 3d + 5h
rearrange the equations and combine like terms. combine the terms with the same variables and add / subtract them.
for example number 1:
9y - 11 + 20 - y
is the same thing as
<em>9y - y</em> <u>+ 20 - 11</u>
and now you can easily combine them:
<em>8y</em> + <u>9</u>
i hope this helps!

Answer:
The third exterior angle is ![103^o](https://tex.z-dn.net/?f=103%5Eo)
Step-by-step explanation:
Given
![\theta = 158^o](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20158%5Eo)
![\alpha = 99^o](https://tex.z-dn.net/?f=%5Calpha%20%3D%2099%5Eo)
Required
The third exterior angle ![(\beta)](https://tex.z-dn.net/?f=%28%5Cbeta%29)
The exterior angles of a triangle add up to 360 degrees.
So:
![\theta + \alpha + \beta = 360^o](https://tex.z-dn.net/?f=%5Ctheta%20%2B%20%5Calpha%20%2B%20%5Cbeta%20%3D%20360%5Eo)
Make
the subject
![\beta = 360^o - (\theta + \alpha)](https://tex.z-dn.net/?f=%5Cbeta%20%3D%20360%5Eo%20-%20%28%5Ctheta%20%2B%20%5Calpha%29)
Substitute known values
![\beta = 360^o - (158^o + 99^o)](https://tex.z-dn.net/?f=%5Cbeta%20%3D%20360%5Eo%20-%20%28158%5Eo%20%2B%2099%5Eo%29)
![\beta = 103^o](https://tex.z-dn.net/?f=%5Cbeta%20%3D%20103%5Eo)
Description:
This will be no solution because when we add 10 to both sides of the equation then simplify it. After that we will subtract 6 from both sides. It will give us no solution. For more info please see the attachment.
Answer: No solution

Answer:
f(x) = 6x +1
Step-by-step explanation:
Differences in x-values (first row) are 1, 1, 1.
Differences in y-values (second row) are 6, 6, 6.
The constant ratio of differences (6/1) tells you the function is linear, and has a slope of m = 6/1 = 6.
Using the first point in the form ...
y = mx + b
we have ...
y = 6x + b
7 = 6·1 + b . . . . (x, y) = (1, 7)
1 = b . . . . . . subtract 6
Then the equation can be written ...
y = 6x +1
In functional form, this is ...
f(x) = 6x +1
