Which of the following must be addressed to improve agriculture in the middle east?
attracting more skilled workers to the agricultural sector
improving the use of farm machinery
upgrading the use of fertilizers and herbicides
all of the above

The answer is all of the above.  All of these methods have been employed in the Middle East to improve and sustain their agricultural development.  The governments in the region have pooled their resources towards improving their agriculture.  They either employ outside help or learn better methods to do so.

1.3x - 2 - (3.3x + 5) = 2x + 1

1.3x - 2 - 3.3x - 5 = 2x + 1

-2x - 7 = 2x + 1

-7 = 4x + 1

-8 = 4x

x = -2
