Question

3x + 5y = 30

Which of the following equations can be used to solve for y in the linear equation above?

Answer 1

`y= - (3x)/(5) + 6`

Explanation:

The given linear equation is

`3x + 5y = 30`

To solve for y, we first subtract 3x from both sides to obtain:

`5y = 30 - 3x`

Divide through by 5

`(5y)/(5) = (30)/(5) - (3x)/(5)`

This simplifies to

`y= 6- (3x)/(5)`

Or

`y= - (3x)/(5) + 6`
