4n-2n+4=-1+17

2n+4=-1+17

-1+17=16

2n+4=16

Move + 4 to the other side. Sign changes from +4 to -4

2n+4-4=16-4

2n=12

Divide by 2 for 2n and 12

2n/2=12/2

n=6

Check answer by using substitution method

4(6)-2(6)+4=16

24-12+4=16

12+4=16

16=16

Answer : n=6

Graham buys 15 pens for $12.75. What is the unit price per pen? Later, at another store, Graham finds 20 of the same pens priced

elena-s [515]

$12.75 divided by 15 pens = $0.85 per pen

$17.40 divided by 20 pens = $0.87 per pen

the first store has the lower price for pens. when you calculate the price of one singular pen, the first store sells them for $0.85 however the second store sells them for $0.02 more ($0.87)
