5d+3v = 3213

5d+3(4d) = 3213

17d = 3213

d = 189

v = 756

so, d+v = ?

**PsyDAG**, Tuesday, October 22, 2013 at 8:35pmThe price of 4 digital = one video.

5 digital + 3 video = 3213

Substitute 4d for v in second equation and solve for d.

5 digital + 3(4 digital) = 3213

Insert that value into the first equation and solve for v. Check by inserting both values into the second equation. Since John buys one of each, add the two values.

Does that make it clearer?
