R = V + 222 Equation 1
R = 2V + 60 Equation 2
Subtract Equation 1 from Equation 2 to get:
0 = V - 162
so:
V = 162, which is the answer you are looking for.
You can also get the number of roses by plugging V into Equation 1
R = 162 + 222 = 384
Check values in Equation 2 to verify solution is correct:
384 = 2 * 162 + 60
384 = 324 + 60
384 = 384 Solution checks out, so you are done
