2/3·z=10/9
answer in proper and improper

z = 5/3 or 1 2/3

Step-by-step explanation:

2/3·z=10/9

Multiply each side by 3/2

3/2*2/3·z=10/9*3/2

z = 30/18

We can simplify by dividing the top and bottom by 6

z = 5/3

Changing to a mixed number

z =1 2/3

1⅔ [OR 5⁄3]

Step-by-step explanation:

2 × ? = 10

3 × ? = 9

That would be 1⅔.

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

41*67/2=1373.5
