Which expression is equivalent to -1/3(6x+15)-3

-78x - 198

Step-by-step explanation:

-13(6x+15) - 3

First, we distribute the -13:

-13 * 6x + (-13) * 15 - 3 = -78x - 195 - 3

Then, we combine like terms:

-78x - 195 - 3 = -78x - 198

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

f(x)=2/3x-8, which give g(x) the greatest value.
