Answer 1

Answer:

-4/5

Step-by-step explanation:

As per the provided information in the given question, we have :

• y/3 + 1 = 11/15

We are asked to find the value of y.

Here, In this equation, Left hand side is equal to right hand side. let's use transposing method and isolate the variable to find the value of it.

So,

$\longmapsto \: \rm{ \dfrac{y}{3} + 1 = \dfrac{11}{15} }$

1 can be written as 1/1.

$\longmapsto \: \rm{ \dfrac{y}{3} + \dfrac{1}{1} = \dfrac{11}{15} }$

Finding a common denominator in L.H.S.

L.C.M of 1 & 3 is 3. So,

$\longmapsto \: \rm{ \dfrac{y \times 1 + {1 \times 3} }{3}= \dfrac{11}{15} }$

Performing Multiplication & addition in numerator of L.H.S.

$\longmapsto \: \rm{ \dfrac{y + {3} }{3}= \dfrac{11}{15} }$

Transposing the denominator of L.H.S to R.H.S. Changing it's sign from (÷) to (×).

$\longmapsto \: \rm{ {y + {3} }= \dfrac{11}{15} \times 3 }$

Performing multiplication in R.H.S.

$\longmapsto \: \rm{ {y + {3} }= 2.2}$

Transposing 3 from L.H.S to R.H.S. Changing it's sign from (+) to (-)

$\longmapsto \: \rm{ {y }= 2.2 - 3}$

Performing subtraction in R.H.S.

$\longmapsto \: \rm{ {y }= - 0.8}$

As a fraction this can be written as,

$\longmapsto \: \rm{ {y }= - \dfrac{8}{10}}$

$\longmapsto \: \rm{ {y }= - \dfrac{4}{5}}$

∴ Hence, The value of y is -4/5.
