X + y = 1.5
x = 1.5 - y
Bring that into 5x + 60y = 35
5 (1.5 - y) + 60y = 35
7.5 - 5y + 60y = 35
62.5y = 35
y = 0.56
Bring that into x + y = 1.5
x + 0.56 = 1.5
x = 1.5-0.56
x = 0.94
Hope this helps.

Answer:
There will be 200g of aluminium.
Step-by-step explanation:
We use a rule of three to solve this question.
However, the relationship between the variables are inverse, which means that we use an inverse rule of three. This means that we are going to multiply the values laterally, instead of diagonally(cross multiplication).
We have these following relationships:
600g aluminum - 40g tim
xg aluminium - 120g tin
Multiplying laterally:
There will be 200g of aluminium.
