Answer:
it is 1/2 of 1
Step-by-step explanation:
Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
Answer:
x = 18.75
Step-by-step explanation:
The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel
3x-10 = 65-x
Add x to each side
3x-10+x = 65-x+x
4x-10 = 65
Add 10 to each side
4x-10+10 = 65+10
4x = 75
Divide each side by 4
4x/4 = 75/4
x = 18.75
Bo they r not bc they look boring
