Answer:
RT = 31
Solve for x:
[tex]x=-22[/tex]
Step-by-step explanation:
==>> The sum of the line is RST
[tex]4x+107+12=RST[/tex]
==>> Since [tex]RST = 2x + 75[/tex], the equation will newly become [tex]4x+107+12=2x+75[/tex]
--
To find [tex]4x+107[/tex], we need to find the x.
==>> [tex]x=-22[/tex]
-- Lets check our work
==>> [tex]4(-22) = -88[/tex]
[tex]-88 + 107 = 19 [RS = 19][/tex]
[tex]RS + ST = 19 + 12 =[/tex] 31
--
[tex]2(-22) = -44[/tex]
[tex]-44 + 75 =[/tex] 31
31 = 31
