To solve the proportion 9
16
5 -5
, we can start by cross multiplying.
(5+5) (s-5)=9•16
Expanding both sides of the
equation, we get: 52 - 25 = 144
Next, we can move the constant
term to the other side: 52 = 144 + 25
Simplifying the right side gives:
s? = 169
To solve for s
, we can take the square root of both sides: s=‡V169
Therefore, the solutions for s
are s = 13
and s = -13. Please note that when
we take the square root of both sides, we get both positive and negative solutions.
