The cost of typesetting a pamphlet is $15 and the cost of paper and printing is 25 cents per copy.
Write an equation that will give the total cost
(T dollars) of printing n copies.
A. T = 15 +0.25n
B. T = 25 + 15n
C. T = 15 + 25n
D. T = 40n

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

50- 250 is correct i did that one too
