35 as many pens as Jen. After Nick bought another 20 pens, he had 14 less pens than Jen. How many pens did Nick have at first?

5 u |
Jen had 14 more pens than Nick in the end. So, if Nick had another 14 pens, he would have the same number of pens as Jen.
5 u = 3 u + 20 + 14
5 u - 3 u = 20 + 14
2 u = 34
1 u = 34 ÷ 2 = 17
Number of pens that Nick had at first
= 3 u
= 3 x 17
= 51
Answer: 51
