~
(x3 + 2x2 - x)-(-x3 + 2x2 + 6)
x3 + 2x2 - x + x3 - 2x2 - 6
x3 + x3 + 2x2 - 2x2 -x - 6
2x3-x-6

Answer:
<h2> <em><u>x = 2.82 (approx.)</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
- 356 = -77 - 99x
=> -77 - 99x = -356
=> -99x = -356 + 77
=> -99x = -279
=> x = 2.8181....
=> <em><u>x = 2.82 (approx.) (Ans)</u></em>
