So let's choose x to represent the number of roses he buys.
That means that x + 3 is the number of daisies.
Now the roses are $3 each, so the total cost of the roses he buys is 3x.
And the daisies are $1 each, so the total cost of the daisies is 1 (x + 3) = x + 3.
So the total amount he spends is the sum of those two, 3x + (x + 3) = 4x + 3.
And we know that that is equal to $39
4x + 3 = 39
Let's solve it:
4x + 3 = 39
4x + 3 - 3 = 39 - 3
4x = 36
4x / 4 = 36 / 4
x = 9
So he buys 9 roses and 12 daisies.
