u=15+2as find the value of S

Start with
[tex]u=15+2as[/tex]
Subtract 15 from both sides:
[tex]u-15=2as[/tex]
Divide both sides by 2a:
[tex]\dfrac{u-15}{2a}=s[/tex]
Answer:
S = [tex]\frac{u - 15}{2a}[/tex]
Step-by-step explanation:
15 + 2as = U
2as = U - 15
as = [tex]\frac{U-15}{2}[/tex]
s = [tex]\frac{U - 15}{2}[/tex] ÷ a
= [tex]\frac{U - 15}{2}[/tex] × [tex]\frac{1}{a}[/tex]
= [tex]\frac{U- 15}{2a}[/tex]
Hope this helps!!!
