please can you answer this question 8th standard maths
​

Answer 1

Step-by-step explanation:

ANSWER:-

$\dfrac{x - 3}{5} - 2 = - 1$

Taking LCM

$\dfrac{x - 3 - 10}{5} = - 1$

$\dfrac{x - 13}{5} = - 1$

$x - 13 = - 1 \times 5$

$x - 13 = - 5$

$x = - 5 + 13$

$x = 8$

is the answer.

Things to Note:-

• A negative number turns positive when it goes towards either side of equal to sign

• A multiplication containing number becomes Division on either side of equal to sign

• Cross multiplication is used to simplify.

• Also, Take LCM first to cross multiply.

Answer 2

Step-by-step explanation:

(( x-3) / 5) - 2 = -1

equate the denominators

(x-3)/5 - 10/5 = -1

(x-13)/5 = -1

x-13 = -1*5

x = -5 + 13

x = 8
