(1) x+y+z=1300
(2) x+y=780 => x = 780 - y
(3) y+z=850 => z = 850 - y
Replace x and z with y in function (1)
780 - y + y + 850 - y = 1300
1630 - y = 1300
y = 330
Therefore, x = 780 - y = 780 - 330 = 450
z = 850 - y = 850 - 330 = 520

Answer:
2.35
Step-by-step explanation:
Here without calculation we can guess that it's value is in between 2 and 3 and closer to 2.
As 7 power 2 is 49 and 7 power 3 is much greater then 98.
98 =
98 -
7
=4.58-1.9=2.35
