If ST=3x+3 and TU=2x+9
it can be solved if ST = TU
then solve first solve for the value of x
ST = TU
3x + 3 = 2x + 9
3x - 2x = 9 - 3
x = 6
now putting the value of x, we can find the value of ST and TU
ST = 3x + 3
= 3 (6) + 3
= 18 + 3
ST= 21
TU = 2x + 9
= 2 (6) + 9
= 12 + 9
TU = 21
the value of ST is 21 and TU is 21 as both are equal

We have that  the value of ST and the value of TU is

ST=21

TU=21

From the question we are told that

[tex]ST=3x+3 \\TU=2x+9.[/tex]

Where T is the mid point

Generally the equation for the T  is mathematically given as

[tex]ST=TU\\\\3x+3 =2x+9.[/tex]

Solving the equation

x=6

Therefore

[tex]ST=3x+3\\\\ST=21[/tex]

And

[tex]TU=2(6)+9.[/tex]

TU=21
