(3x +1) + (2x -2) = 64
5x = 65
x = 13
RS = (3x +1) = (3*13) +1 = 40
ST = (2x -2) = (2*13) -2 = 24

SOLVING: (According to the image)
[tex]\overline{RS} + \overline{ST} = \overline{RT}[/tex]
[tex](3x+1) + (2x-2)=64[/tex]
3x + 1 + 2x - 2 = 64
3x + 2x = 64 - 1 + 2
5x = 65
[tex]x = \frac{65}{5} [/tex]
[tex]\boxed{\boxed{x = 13}}\end{array}}\qquad\quad\checkmark[/tex]
