How do I solve this equation? 3|13-2t|=15
Nikolay [14]
3 |13 - 2t | =15 ⇒ |13-2t| = 15\div3 ⇒ \boxed {|13-2t| = 5}

\hbox {We have two equations : 1. } |13-2t|=5 
                                               2.|13-2t|=-5

\hbox{The first: } ⇒ 13-2t=5 ⇒ 2t=13-5 ⇒ 2t=8 ⇒ \boxed {t=4}

\hbox { The second: } 13-2t=-5 ⇒ 2t=13-(-5)=18 ⇒ \boxed {t=9}

the measure of an angle is five degrees greater than six times its supplement. what is the measure of the larger angle?
Law Incorporation [45]
Let the measure of the smaller angle be x, then the larger angle is 5 + 6x and
x + 5 + 6x = 180
7x + 5 = 180
7x = 180 - 5 = 175
x = 175/7 = 25

The larger angle is 5 + 6(25) = 5 + 150 = 155 degrees.
