Explanation:
#"we are given "t=(12(s-r))/r#
#"multiply both sides by "r#
#rt=cancel(r)xx(12(s-r))/cancel(r)#
#rt=12(s-r)larrcolor(blue)"distribute"#
#rt=12s-12r#
#"add "12r" to both sides"#
#rt+12r=12s#
#"take out "r" as a "color(blue)"common factor"#
#r(t+12)=12s#
#"divide both sides by "(t+12)#
#r=(12s)/(t+12)#
Explanation:
Making
Right now, we have
We don't want
Distributing the
To solve for
Both left side terms have an
Our last step would be to divide both sides by
Hope this helps!
