Adding equation (1) and (2)

4x+5y-4x-4y=-8+4

y=-4

Substitute y=-4 in equation (1) or (2)

4x+5(-4)=-8

4x-20=-8\\4x=-8+20\\4x=12\\x=3

Daniel is paid $10 per week for selling newspaper subscriptions. He is also paid $3.50 for each new customer (x) that signs up f
Aliun [14]
Alright so, since it says that he eats at least $10 dollars no matter what we can basically leave that alone. next week have $3.50 for every new customer (x) so we could write this as $3.50x. and lastly we have Y the amount he will earn every week.

so the equation would be $10+$3.50x=Y.

if we had more information we might be able to solve for Y but since it doesn't tell us how many he sold we would leave it like that.
