Answer:
The solution is [tex]x = 7[/tex],
Step-by-step explanation:
Equation:
[tex]6x - 7 + 20x + 5 = 180\textdegree[/tex]
-Combine like terms:
[tex]6x - 7 + 20x + 5 = 180\textdegree[/tex]
[tex]26x - 2 = 180\textdegree[/tex]
Add both sides by 2:
[tex]26x - 2 + 2 = 180\textdegree + 2[/tex]
[tex]26x = 182\textdegree[/tex]
-Divide both sides by 26:
[tex]\frac{26x}{26} = \frac{182\textdegree}{26}[/tex]
[tex]x = 7[/tex]
So, the answer is [tex]x = 7[/tex].
