Let x= measure of angle 1
Let y= measure of angle 2
This is solving a system of equations
3x=30+ 5y which can also be written
3x-5y=30, and
2x+2y=180
There are a few ways to solve this, like solving for x in one of the equations and plugging it in for x in the other equation, but here is another way:
2(3x-5y)=2*30
3(2x+2y)= 3*180
6x-10y=60
6x+6y=540, and now subtract to get rid of x
0-16y=-480
Y=30
Plug it back in to either equation and you get x=60
Your probability of picking a white ball is going to be 67%
4x + 2y = 8
When x = -2: 4x + 2y = 8
4(-2) + 2y = 8
-8 + 2y = 8
+ 8 + 8
2y = 16
2 2
y = 8
(x, y) = (-2, 8)
When x = 1: 4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
- 4 - 4
2y = 4
2 2
y = 2
(x, y) = (1, 2)
When x = 3: 4x + 2y = 8
4(3) + 2y = 8
12 + 2y = 8
- 12 - 12
2y = -4
2 2
y = -2
(x, y) = (3, -2)

Hope this helped! Have a great day. :)</span>
So you make common denominators 5/10 + 6/100 so it would be 5x10/10x10 would become 50/100 + 6/100
and would equal 56/100.
