Question

7y/5 = y - 4 solve this equation

Answer 1

The equation is:

7y/5 = y-4

7y = 5(y-4)

7y = 5y-20

7y-5y = -20

2y = -20

y = -10

Thanks for watching the answer.

Answer 2

Answer:

=> y = -10

Step-by-step explanation:

Given that:-

$\frac{7y}{5}=y-4$

To find:- The value of the expression:

Here we will use the transposition method.

First of all, we have to identify the variables and the constants.

Then solve the expression of both sides by using various mathematical operations.

As we have,

=> $\frac{7y}{5}=y-4$

Subtract $y$ from both sides,

=> $\frac{7y}{5}-y=y-4-y$

=> $\frac{7y}{5}-\frac{5(-y)}{5} =y-4-y$

Simplifying it further, we get

=> $\frac{7y+5(-y)}{5} =y-4-y$

$=> \frac{2y}{5}=- 4$

Now, multiply both sides by $5$

$=> \frac{2y}{5}\times 5=- 4\times 5$

=> $2y=-20$

Divide both sides by $2$,

=> y = -10

Hence, the required solution is -10.
