5 tins of soup have a total weight of 1750 grams. 4 tins of soup and 3 packets of soup have a total weight of 1490 grams. Work out the total weight of 3 tins of soup and 2 packets of soup.

Step 1 - Find the weight of 1 tin of soup: 1750 ÷ 5 = 350 Step 2 - Use this number (350) to find the weight of 1 packet of soup: (4x350) + 3P = 1490, 3P = 90, P=30Step 3 - Work out weight of 4 tins of soup and 3 packets of soup: (3x350) + (2x30) = 1050 + 60 = 1110Answer: 1110g
