Respuesta :

Given cy - 7 = 5d + 3y, we solve for y as follows:

cy - 3y = 5d + 7

y(c - 3) = 5d + 7

y = (5d + 7) / (c - 3)

For this case we have the following equation:

[tex] cy-7 = 5d + 3y
[/tex]

We must clear the value of y.

For this, we follow the following steps:


1) We place the variables on one side of the equation and the constant terms on the other side of the equation:

[tex] cy-3y = 5d + 7
[/tex]


2) We make the common factor "y" on the left side of the equation:

[tex] y(c-3) = 5d + 7
[/tex]


3) We move to divide c-3 on the right side of the equation:

[tex] y = \frac{5d + 7 }{c-3} [/tex]


Answer:

The value of y is given by:

[tex] y = \frac{5d + 7 }{c-3} [/tex]
