Answer:

[tex]y= - \frac{3x}{5} + 6[/tex]

Step-by-step explanation:

The given linear equation is

[tex]3x + 5y = 30[/tex]

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

[tex]5y = 30 - 3x[/tex]

Divide through by 5

[tex] \frac{5y}{5} = \frac{30}{5} - \frac{3x}{5} [/tex]

This simplifies to

[tex]y= 6- \frac{3x}{5} [/tex]

Or

[tex]y= - \frac{3x}{5} + 6[/tex]
