Question

5(y-1)=3(2y-5)-(1-3y)


last one :D

Answer 1

Answer:

5 ( y - 1 ) = 3 ( 2 y - 5 ) - ( 1 - 3 y )

⇒ 5 y - 5 = 6 y - 15 - 1 + 3 y

⇒ 5 y - 6 y = - 16 + 5 + 3 y

⇒ - y = - 11 + 3 y

⇒ - y - 3 y = - 11

⇒ - 4 y = - 11

⇒ y = - 11 / - 4

⇒ y = 11 / 4

Explanation :

→ We are given an equation and we need to find the value of 'y' .

→ First we reorder the terms .

→ Then group the common terms with same coefficients .

→ Keep the unknown value on the left hand side .

→ Keep the numeric value on the right hand side .

Answer 2

$5(y - 1) = 3(2y - 5) - (1 - 3y)$

$5y - 5 = 6y - 15 - 1 + 3y$

$5y - 5 = 9y - 16$

$5y - 9y = - 16 + 5$

$- 4y = - 11$

$4y = 11$

$y = \frac{11}{4}$
