List the multiples of 12 and 16

Multiples of 12: 12, 24, 36, 48, 60
Multiples of 16: 16, 32, 48, 64, 80

So, the LCD of 12 and 16 is 48.

Least Common Denominator is the same thing as Least Common Multiple.

The least common denominator of 5/12 and -9/16

The answer is 48.

Now, we have to change the numerators also to make this a equal fraction to the first ones we had.

5*4 = 20
12*4 = 48

20/48

-9*3 = -27
16*3 = 48

-27/48

Solve the following system of equations algebraically: 4x - 5y = 18 3x – 2y = 10

fiasKO [112]

Answer:

Step-by-step explanation:

Given the 2 equations

4x - 5y = 18 → (1)

3x - 2y = 10 → (2)

Multiplying (1) by 3 and (2) by - 4, then adding will eliminate the x- term

12x - 15y = 54 → (3)

- 12x + 8y = - 40 → (4)

Add (3) and (4) term by term to eliminate x, that is

- 7y = 14 ( divide both sides by - 7 )

y = - 2

Substitute y = - 2 into either of the 2 equations and solve for x

Substituting into (1)

4x - 5(- 2) = 18

4x + 10 = 18 ( subtract 10 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

solution is (2, - 2 ) → D
