\qquad\qquad\huge\underline{{\sf Answer}}

Here we go ~

\qquad \sf  \dashrightarrow \:4 - 7x = 1 - 6x

\qquad \sf  \dashrightarrow \:4  - 1 = 7x- 6x

\qquad \sf  \dashrightarrow \:x = 3

so, we got the value of x as 3

Answer:

x = 3

Explanation:

⇒ 4 - 7(x) = 1 - 6(x)

⇒ -7(x) + 6(x) = 1 - 4

⇒ -(x) = -3

⇒ x = 3

Check:

  • 4 -7(3) = 1-6(3)
  • 4 - 21 = 1 - 18
  • -17 = -17

<u>Hence</u>, x = 3 confirmed as L.H.S = R.H.S

Person A can paint the neighbor's house 6 times as fast as Person B. The year A and B worked together it
uranmaximum [27]

Person A takes 2.3 days to paint the house working alone

Person B takes 13.8 days to paint the house working alone

<em><u>Solution:</u></em>

Let "x" be the number of days it takes person A  to paint the house

Person A can paint the neighbor's house 6 times as fast as Person B

Therefore.

Number of days it takes person B to paint the house = 6x

Their rates of painting are added to get  the rate working together

\frac{\text{1 house}}{\text{x days}} + \frac{\text{1 house}}{\text{6x days}} = \frac{\text{1 house}}{\text{2 days}}

\frac{1}{x} + \frac{1}{6x} = \frac{1}{2}\\\\\frac{1 \times 6}{6x} + \frac{1}{6x} = \frac{1}{2}\\\\\frac{7}{6x} = \frac{1}{2}\\\\\ x = \frac{7}{3}= 2.3

Thus person A takes 2.3 days to paint the house working alone

Person B = 2x = 6(2.3) = 13.8

Thus person B takes 13.8 days to paint the house working alone
