The value of -18/15 · 20/24 is .

I think that the value is -1/2

Because firstly you have to make it easier to read like that : (-1x3x2x3)x(2x5x2) / ( 3x5)x(3x4x2)

Then you can just cross out the one you see in the numerator and denominator . Then you have something like -1/2 with what you didn’t cross out.

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
