-2x = 12.......divide both sides by -2
x = -6
division property of equality

Answer:
59 degrees
Step-by-step explanation:
The total amount of degrees for a triangle must add up to 180 degrees.
74 + 47 = 121
180 - 121 = 59
Thus meaning the missing exterior angle measure is 59 degrees.
I hope this helped! :)

Answer:
![\boxed{ \bold{ \huge{ \boxed{ \sf{r = 1.9}}}}}](https://tex.z-dn.net/?f=%20%20%5Cboxed%7B%20%5Cbold%7B%20%5Chuge%7B%20%5Cboxed%7B%20%5Csf%7Br%20%3D%201.9%7D%7D%7D%7D%7D)
Step-by-step explanation:
![\sf{7(r + 1) = 20.3}](https://tex.z-dn.net/?f=%20%5Csf%7B7%28r%20%2B%201%29%20%3D%2020.3%7D)
Distribute 7 through the parentheses
⇒![\sf{7r + 7 = 20.3}](https://tex.z-dn.net/?f=%20%5Csf%7B7r%20%2B%207%20%3D%2020.3%7D)
Move 7 to right hand side and change it's sign
⇒![\sf{7r = 20.3 - 7}](https://tex.z-dn.net/?f=%20%5Csf%7B7r%20%3D%2020.3%20-%207%7D)
Subtract 7 from 20.3
⇒![\sf{7r = 13.3}](https://tex.z-dn.net/?f=%20%5Csf%7B7r%20%3D%2013.3%7D)
Divide both sides of the equation by 7
⇒![\sf{ \frac{7r}{7} = \frac{13.3}{7} }](https://tex.z-dn.net/?f=%20%5Csf%7B%20%5Cfrac%7B7r%7D%7B7%7D%20%20%3D%20%20%5Cfrac%7B13.3%7D%7B7%7D%20%7D)
Calculate
⇒![\sf{r = 1.9}](https://tex.z-dn.net/?f=%20%5Csf%7Br%20%3D%201.9%7D)
Hope I helped!
