Basic geometry question. Help anyone please

How do I write an equation for this: The measure of an angle is 110 degrees more than the measure of its supplement. What is the measure of the angle?

let x = an angle

then,

(180 - x) = the supplement of an angle

x = (180 - x) + 110

2x = 290

x = 145º

the supplement of 145º is 35º

check

qed

x measure of the angle
x+x+110=180
2x=70
x=35

proof
35+(35+110)=180

angle is A, its supplement is 180-A
A = 110 + 180-A
A = 145
