The cost of Roses and vase purchased by Gordon and Aaron can be gotten by translating word problem to relatable mathematical expression
Rose cost $3 while vase cost $15 each
let roses be x
and vases be y
For Gordon, the expression mathematically is
8x +y = 39 -----------1
For Aaron, the expression mathematically is
5x + y = 30 ----------2
Let us solve 1 and 2 simultaneously
subtract 2 from 1
8x +y = 39
- 5x + y = 30
3x = 9
x= 9/3
x = 3
put x = 3 in equation 1 to find y
8(3) + y = 39 ----------1
24 + y = 39
y = 39-24
y = 15
