What does this solve 3k - 11 = -34

k = -23/3

Step-by-step explanation:

3k - 11 = -34

Add 11 to each side

3k - 11+11 = -34+11

3k =-23

Divide each side by 3

3k/3 = -23/3

k = -23/3

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

good luck on your studies! : )
