Question 85917
1.  let x equal the first side, so x+7 equals the second side and 2x-6 equals the third side
x+(x+7)+(2x-6)=69 ... 4x+1=69 ... x=17 ...x+7=24 ...2x-6=28


2.  let x equal $5 bills, so 3x equals $1 bills and 60-4x equals $10 bills
(5*x)+(1*3x)+(10*(60-4x))=184 ... 5x+3x+600-40x=184 ... -32x=-416 ... x=13 ... 3x=39 ... 60-4x=8
