I really need help on solving literal equations, here's and example of one 3x +2y =9 solve for y
14w + 15x = y -21 solve for w I basically need help on problems like these thank you so much if you can help! I'm new to this website by the way and Im really enjoying it so far ?

Alright here we go

1)
3x +2y =9 solve for y, So we have to find the value of "y" in other words
2y = 9 - 3x
y = 9/2 - 3x/2

2)
14w + 15x = y -21
14w = y - 21 - 15x
w = y/14 - 21/14 - 15x/14
w = y/14 - 3/2 - 15x/14

Hope it helps
