Supplementary means they add up to 180, so you can write an equation:
3x + 2x - 25 = 180
5x - 25 = 180
+ 25
5x = 205
÷ 5
x = 41

Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
x + y = 3
x = 3 - y
y = 2x - 15
y = 2(3 - y) - 15
y = 6 - 2y - 15
y = -2y - 9
3y = -9
y = -3
y = 2x - 15
-3 = 2x - 15
-2x = -12
x = 6
So...
The answer is: (6, -3)
If you have a picture of the problem I can answer it so just send a pic of the math problem
That's false.
Let's see an instance:
10% of 300=30
20% of 100=20
It doesn't work here so it's false
