Question

21-2x=5y















My love for you is like a concave up function because it is always increasing.

Answer 1

what is your question ?

Answer 2

solve for y and x

Answer 3

21 - 2x = 5y --- divide both sides by 5
21/5 - 2/5x = y

21 - 2x = 5y --- subtract 21 from both sides
-2x = 5y - 21 --- divide both sides by -2
x = -5/2y + 21/2
