What is 4/9 and 17/18 renamed using least common denominator?

8/18 & 17/18 is your answer.

Step-by-step explanation:

Find common denominators for both (you cannot simplify). Note that what you do to the denominator, you must do to the numerator. Find multiples of each number:

9: 9, 18

18: 18

The first least common denominator you get is 18. Solve:

(4/9)(2/2) = 8/18

8/18 & 17/18 is your answer.

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
