The only thing you can do with this expression is to factor a 5 out of the two terms: we have

Answer:
8x + 108 = 9
Step-by-step explanation:
Given
x + 9 = 
Multiply through by the lowest common multiple of 3 and 4, that is 12 to clear the fractions.
8x + 108 = 9 ← equivalent equation with no fractions
what about using 20-30-40-5
Step-by-step explanation:
the sequence is that you are skipping ten to get the second nb which is 30 and keep on going on to get 50
Measure of angle 2 would be 130 degrees because since it forms a linear pair the two angles added together have to equal 180 degrees so
180 - 50 = 130
5z+7=32
5z+7-7=32-7
5z/5=25/5
z=5
