Answer:
B
Step-by-step explanation:
∠ ABC = 9x + 5 ( alternate angles )
∠ ABC and ∠ DCB are sam- side interior angles and sum to 180° , that is
9x + 5 + 16x = 180
25x + 5 = 180 ( subtract 5 from both sides )
25x = 175 ( divide both sides by 25 )
x = 7
Then
∠ ABC = 9x + 5 = 9(7) + 5 = 63 + 5 = 68° → B
Say you have this problem.
4x=2x-4
First you would combine your like terms.
4x = 2x-4
-2x=-2x-4
---------------
2x=-4
Next you would divide
2x =-4
÷ -4 =-4
--------------
x = 0.5
