Make y the subject of: 4y-2x=17 Please help?

Question

 I need help with my algebra work, i'm home schooled and my mum doesn't know how do do algebra, please help! 

Make y the subject of:

4y-2x=17

    And  

2y over 3-x=z

Thank you!! 

 

 

Answer 1

I think you mean "solve the equation for y".

 

4y-2x = 17

 

 

Add 2x to both sides:

 

4y - 2x (+2x) = 17 (+2x)

 

4y = 2x + 17  (it's okay to switch the order since it's addition)

 

 

Divide both sides by 4:

4y/4 = 2x/4 + 17/4

 

y =  x/2 + 17/4

 

Answer 2

Remember whatever you do to one side of an equation, you must also do to the other side!

4y-2x=17

remove -2x from the left side by adding 2x and do to the right side, also.

Result: 4y=2x+17

Divide the left side by 4 to get y alone and do to the other side, also.

y=1/2x+17/4
