For 
as

now, we can draw a number line and locate y=23
and then shade left side of 23 region
that would be solution
Answer:
what is the question asked?
Step-by-step explanation:
So the sides ML and MN are exactly the same. Your equation would look something like this...
3x = x + 10
You first subtract x from both sides to isolate the variable.
2x = 10
Divide 2 from both sides.
x = 5
5 is the length of MN.
I hope this helps love! :)
