On monday at the county fair jared played a game and won 75 tickets on tuesday he won 105 tickets on wednesday he won 127 but then spent 250 of them on a prize. how many more tickets does jared need to win to get a prize that costs 150 tickets

93

Step-by-step explanation:

NOTE: "won" means add, "spent" means subtract

Monday: + 75

Tuesday: Monday + 105   = 75 + 105   = 180

Wednesday: Tuesday + 127 - 250   =   180 + 127 - 250   = 57

Jared has 57 but needs 150

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
