Hello!
<span>The constant of variation is xy. XY=23. If X=7 then Y=23/7.
</span>
So as we can see, the stated inverse variation can be represented as the equation y = k/x. ===> k = 23 & x = 7 ⇒ y = 23/7. <====

Answer:
x = 5
Step-by-step explanation:
The difference between consecutive terms will be equal , then
a₂ - a₁ = a₃ - a₂ , that is
x + 9 - (3x - 2) = 2x + 5 - (x + 9) ← distribute parenthesis on both sides
x + 9 - 3x + 2 = 2x + 5 - x - 9 , simplify both sides
- 2x + 11 = x - 4 ( subtract x from both sides )
- 3x + 11 = - 4 ( subtract 11 from both sides )
- 3x = - 15 ( divide both sides by - 3 )
x = 5
You have to use the equation which has just slipped my mind. It say x1-y1 over x2-y2. Then you will find x. I am so sorry this equation name slipped my mind. If I remember I will let you know.
-26 is not an inequality. It's just a number. Maybe there was
another part of it that you forgot to copy.
