y=5a-3b+c, if a=12, b=4, and c=8
y=5*12-3*4+8
y=60-12+8
y=56 ans.

y=5a-3b%2Bc Start with the given expression.


y=5%2A12-3%2A4%2B8 Plug in a=12, b=4, and c=8


y=60-3%2A4%2B8 Multiply 5 and 12 to get 60.


y=60-12%2B8 Multiply 3 and 4 to get 12.


y=48%2B8 Subtract 12 from 60 to get 48.


y=56 Add 48 and 8 to get 56.


So 5a-3b%2Bc=56 when a=12, b=4, and c=8
