Question

solve for y , 7 - y = 3(5 – y)​

Answer 1

Answer:3/2

Step-by-step explanation:

7-y= 3(5-y)

7y=15-3y

transposing 3y to LHS

7y+3y=15

10y=15

transpoing 10 to RHS

Y=15/10

=3/2

Answer 2

Answer:

=> The value of y is 4.

Step-by-step explanation:

Given that:-

$7 - y = 3(5 -y)$

To find:- The value of the expression,

To find the value of x, we must apply the transposition method:

As we have,

=> $7 - y = 3(5 -y)$

Distributing the terms, we get

=> $7 - y = 15 -3y$

Rearranging the terms, we get

=> $-y+7=-3y +15$

Now subtract both sides by $7$,

=> $-y+7-7=-3y +15-7$

Simplifying it further, we get

=> $-y=-3y +15-7$

=> $-y = -3y + 8$

Now add both sides by $3y$,

=> $-y +3y= -3y + 8+3y$

=> $2y = 8$

Divide both sides by $2$, we get

=> $y = 4$

Hence, the required solution is 4.
