\dfrac{6}{3}+\left(-\dfrac{1}6\righ t)= 3 6 +(− 6 1 )=start fraction, 6, divided by, 3, end fraction, plus, left parenthesis, minus, start fraction, 1, divided by, 6, end fraction, right parenthesis, equals

1 5/6

Step-by-step explanation:

We are given:.6/3 + (- 1/6)

We have the rule

+ × - = -

Hence

6/3 - 1/6

LCM of the Denominators = 6

=(6 × 2) -(1 × 1)/6

= (12 -1)/6

= 11/6

= 1 5/6

2 x t divided by n

step-by-step explanation:

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
