-13/4 =n

Step-by-step explanation:

-5/2 = 3/4 +n

Subtract 3/4 from each side

-5/2 - 3/4 = 3/4 +n-3/4

-5/2 -3/4 =n

Get a common denominator

-5/2 *2/2 - 3/4=n

-10/4 - 3/4 = n

-13/4 =n

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
