1/2 (6a + 8)=14

a= 10/3

Step-by-step explanation:

multiply both sides by 2

get 6a +8 =28

subtract 8 from both sides

you get 6a=20

divide 6 both sides and 10/3.

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
