Which equation represents the solution to this system? x+y+z=350
x+y-z=130
2x+3y+2z=790

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

payback

6+6=12 so that just tells you what it is one half is 6 the next one is 6
