Answer: 5x - 9 = 6
Step-by-step explanation:
x = 3
2(3) - 8 -= 5 --> 6 - 8 =5 (false)
9(3) + 4 = -31 --> 27 + 4 = -31 (false)
6(3) - 9 = 57 --> 18 - 9 = 57 (false)
5(3) - 9 = 6 --> 15 - 9 = 6 (true)
Answer:
5x-9 = 6
Step-by-step explanation:
5x−9=6
Add 9 to both sides.
5x=6+9
Add 6 and 9 to get 15.
5x=15
Divide both sides by 5.
x= 15/5
Divide 15 by 5 to get 3.
x=3

divide each side by 2
x = 66.1
find the measure of the other angle
66.1 - 42.2 = 23.9
