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!!!
