Answer:
20x + 17 = 77 --> Addition Property of Equality:
You are adding (Addition Property) 4x to both sides of the equal sign (Equality).
20x = 60 --> Subtraction Property of Equality:
You subtracted (Subtraction Property) 17 from both sides of the equal sign (Equality).
x = 3 --> Division Property of Equality:
You divided (Division Property) 20 from both sides of the equal sign (Equality) to completely isolate the variable x.

Answer:
x= 13.5
Step-by-step explanation:
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
<em>Check:</em>
f(x) = 2x + 9
f(13.5) = 2(13.5) + 9= 27 + 9 = 36
Answer:
3 = 92 degree 4 = 88 degree
Step-by-step explanation:
