The line has 3 points - R, S, and T.
If RS = 3x + 1, ST = 2x - 2, and RT = 64, find the value of x.
Find RS and ST.
Thanks!

The distance from R to T is 64 units.
The distance from R to S to T is 3x+1 + 2x-2
so 3x+1+2x-2 =64
so 5x-1 =64
so 5x = 65
so x = 13
3x+1 =RS =40
2x-2 = ST = 24

3x + 1 + 2x - 2= 64

R___S___T
RT = 64
RS + ST = RT
(3x+1)+(2x-2)=64 *Add all like terms on left side of equation.
=(5x-1)=64 *Start to isolate the variable by adding the 1 on both sides of the equation.
=(5x)=65 *Isolate the variable by dividing the 5.
=(x)=13 *Answer is 13.
