Lets represent a tin of beans as 
and a jar of jam as 
.
Therefore
3b+4j=2080 and 5b=2000.
Now we can say that b=400.
Substitute b in 3b+4j=2080 for 400.
3*400+4j=2080
Simplify
1200+4j=2080
4j=880
j=220.
Therefore
1 tin of beans is 400 grams and 1 jar of jam is 220 grams.

Answer:
-12m-6n
Step-by-step explanation:
Let's break this down systematically
Start:
8m + 2n - 4(5m - 2n)
Use the distributive property
8m + 2n - <u>4(5m - 2n)</u>
8m + 2n - 20m - 8n
Match like terms <em>m </em>and <em>n</em>
8m - 20m = -12m
2n - 8n = -6n
<u>-12m-6n</u>
