Answer: x=y+11
Step-by-step explanation:
Equation: x−y=11
Step 1. You need to add y to both sides.
x−y+y=11+y
x=y+11
Answer:
x=y+11
In this problem the big angle will be equal to two times the smaller angle so the correct expression is:

Now we can rewrite the equation so:
Answer:
95
Step-by-step explanation:

10th term of the sequence is 95.
The equivalent expression is 10x+5y-15z
