2014 - ( 56 + a x 4 - 9 x 8 ) = 2010
2014 - ( 56 + a x 4 - 72 ) = 2010
56 + a x 4 - 72 = 4
56 + a x 4 = 68
a x 4 = 12
a = 12 : 4
a = 3
2014 - ( 56 + a x 4 - 72 ) = 2010
56 + a x 4 - 72 = 4
56 + a x 4 = 68
a x 4 = 12
a = 12 : 4
a = 3
2014-(7*8+a*4-45/5*8)=2010 2014-(56+a*4-9*8)=2010 2014-(56+a*4-72)=2010 (56+a*4)-72=2014-2010 (56+a*4)-72=4 (a*4)-72=56-4 (a*4)-72=52 a*4=72-52 a*4=20 a=20/4 a=5
2014-(7*8+5*4-45/5*8)=2010
2014-(7*8+5*4-45/5*8)=2010
