Question 881141
x = number of 6 pound boxes
35 - x = number of 10 pound boxes {there are 35 boxes}


6x + 10(35 - x) = 262   {weight of each box multiplied by number of boxes equals total weight}
6x + 350 - 10x = 262 {used distributive property}
-4x + 350 = 262 {combined like terms}
-4x = -88 {subtracted 350 from each side}
x = 22 {divided each side by -4}
35 - x = 13 {substituted 22, in for x, into 35 - x}


22 six pound boxes
13 ten pound boxes
