You can put this solution on YOUR website! Let x be the first number
x+2 be the second
x+4 be the third
x+6 be the fourth
(x)+(x+2)+(x+4)+(x+6) = 56 combine similar terms
x+x+x+x = 56-2-4-6
4x = 44 divide both side by 4 to get x
x= 11
x+2=?
11+2= 13
x+4=?
11+4= 15
x+6=?
11+6=17
CHECKING
11+13+15+17= 56
56 = 56
