y=2x-3 an x+y=3
subsitution
since y=2x-3, put (2x-3) wherever you see y
put taht in the other equation
x+y=3
x+(2x-3)=3
x+2x-3=3
3x-3=3
add 3 to both sides
3x=6
divide by 3
x=2
subsitute back
y=2x-3
y=2(3)-3
y=6-3
y=3
so the solution set in (x,y) form is (2,3)

Answer: the Jones family paid $164
Step-by-step explanation:
Let x represent the one time charge that smith lake boat rentals charge for cleaning.
The bengal family rented a boat from 11 am- 6:30pm and paid $226.50. This means that the number of hours for which they rented the boat is
11 - 6:30/= 7.5 hours
Therefore,
25 × 7.5 + x = 226.5
187.5 + x = 226.5
x = 226.5 - 187.5
x = $39
If the jones family rented a boat from 8am-1pm, the number of hours would be 5 hours.
The amount that they paid is
39 + 5 × 25 = 39 + 125
= $164
