Solve the equation | - x-3.1415926 | + | - y + 11 / 8 | - 2y-7.13 | = 0

|X|-|X-3.1415926|=0 and |Y+11/8|-|2Y-7.13|=0
X=-X+3.1415926
X=1.5707963
Y+11/8=2Y-7.13 OR Y+11/8=-2Y+7.13
Y=8.505 OR Y=1.918

Given x + y = 8, y + x = 12, x + Z = 10, then what is x + y + Z equal to?

15 (the second is y + Z = 12)
x=3
y=5
z=7

If x + y = 8, y + Z = 12, x + Z = 20, what is x + 2Y + Z equal to

X+Y=8,
Y+Z=12
The sum of the two formulas is as follows:
X+2Y+Z=8+12=20

X + y = 16, y + Z = 12, Z + x = 10, how much is x, y, Z equal?

x+y=16 ①
y+z=12 ②
z+x=10 ③
① - 2, x-z = 4, 4
④ The solution is x = 7
Substituting ①, the solution is y = 9
Substituting into 3, the solution is Z = 3
