Question

Find the value of X

Answer 1

Answer:

$x = - \frac{7}{2} = - 3.5$

Step-by-step explanation:

Given:

$\frac{440x + 440 x - 77}{ \frac{440x}{440} + \frac{440x - 770}{660} } = 550$

$= \frac{880x - 770}{x + \frac{110(4x - 7)}{110 \times 6} }$

$= \frac{880x - 770}{x + \frac{4x - 7}{6} } = \frac{880x - 770}{ \frac{6x + 4x - 7}{6} } = \frac{880x - 770}{ \frac{10x - 7}{6} }$

$= 880x - 770 \times \frac{6}{10x - 7}$

$880x - 770 = 550 \times \frac{10x - 7}{6}$

$880x - 770 = \frac{5500x - 3850}{6}$

$6(880x - 770) = 5500x - 3850 \\ = 5280x - 4620 = 5500x - 3850$

$5280x - 5500x = 4620 - 3850$

$- 220 x= 770$

$x = \frac{770}{ - 220} = - \frac{7}{2}$

Answer 2

Answer:

here is your answer

Step-by-step explanation:

440x/440 + 440-770/660 = 550

x + 4-7/6 = 550

x+(-3/6) = 550

x+(-1/2) = 550

x - 1/2 =550

x - 1 = 550×2

x - 1 = 1100

x= 1100+1

x= 1101
