V + 47 - 5V = 287
gather V's together
47 - 4V = 287
subtract 47 from both sides
47 - 47 - 4V = 287 - 47
- 4V = 240
divide both sides integers by - 4
(- 4/ - 4)V = 240/- 4
V = - 60
-----------------check in original equation
( - 60 ) + 47 - 5( - 60) = 287
- 13 + 300 = 287
287 = 287

This equation is not possible. Two plus three plus four plus five does not equal 287. The system has no solution.
105 + 66 + 287 + 81 = 539
287/8 equals 35 7/8.
The answer is 2,882

290 plus 500
287 + 491 + 200 + 500 + 300 + 500 + 280 + 400 + 290 + 490 = 3738
350 - 18% = 287
