Answer:
They are supplementary angles so they add up to make 180°
So you do the reverse
180°-100°=x
80°=x

Answer:

Step-by-step explanation:
So we have the equation:

And we want to write it in terms of m.
So, let's subtract b from both sides:

Now, let's divide both sides by x:

And we're done!
I don’t know man I’m sorry
2x + 3y = 45
x + y = 10......y = 10 - x
2x + 3(10 - x) = 45
2x + 30 - 3x = 45
-x + 30 = 45
-x = 45 - 30
-x = 15
x = -15 <====
and y = 25
