Acircular piece of fabric has a radius of 1.2 feet. the fabric sells for $5.40 per square foot. what is the total cost of the circular piece of fabric? a. $6.48 b. $20.35 c. $24.42 d. $40.69

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

dude thats to long figure it
