Question

Can someone plz help with 21?? Thanks!

Answer 1

Answer:

option 4

Step-by-step explanation:

$\frac{2}{3}$ ($\frac{1}{4}$ x - 2) = $\frac{1}{5}$ ($\frac{4}{3}$ x - 1) ← distribute parenthesis on both sides

$\frac{1}{6}$ x - $\frac{4}{3}$ = $\frac{4}{15}$ x - $\frac{1}{5}$

Multiply through by 30, the LCM of 6, 3, 15, 5

5x - 40 = 8x - 6 ( subtract 8x from both sides )

- 3x - 40 = - 6 ( add 40 to both sides )

- 3x = 34 ( divide both sides by - 3 )

x = - $\frac{34}{3}$ = - 11.333..

Answer 2

Answer:

4) -11.3...

Step-by-step explanation:

distribute both sides to get (1/6)x - (4/3) = (4/15)x - (1/5)

move the variables to one side and the constants to the other: ((4/15) - (1/6))x = (-(4/3) + (1/5))

simplify to get (1/10)x = (-17/15) multiply everything by 10 to get x=-34/3 or -11.33333333333333333...
