Question

15 (y - 4) - 2 (y - 9) + 5 (y+6) = 0 Find y .​

Answer 1

Question:

15 (y - 4) - 2 (y - 9) + 5 (y+6) = 0 Find y .

Solution:

We have

15 (y - 4) -2( y - 9) + 5 (y +6) =0

Simplifying

15y - 60 -2y +18 +5y + 30 =0

Re arranging

15y -2y +5y + 18 +30 -60 =0

Adding and subtracting like terms

20y -2y +48 -60 =0

=> 18y - 12 =0

=> 18y = 12

$= > y = \frac{18}{ 12} \\ \\ = > y = \frac{2}{3}$

Hence, the value of y is 2/3

$15(y - 4) - 2(y - 9) + 5(y + 6) = 0 \\ ⇒15y - 60 - 2y + 18 + 5y + 30 = 0 \\ ⇒18y = 60 - 18 - 30 \\ ⇒18y = 12 \\ ⇒y = \frac{18}{12} \\ ∴y = 1.5$
