Answer:
u need decimals for all of them or u at least use them a lot
Step-by-step explanation:
You need to have variables one one side and constants on the other. ax - ax + by = c - ax
by = c - ax
by/b = (c - ax)/b
y = (c - ax)/b
1/4
There are 100 pence in a pound, so 2 pounds is 200 pence. 50 is 1/4 of 200.
