If ST = 3x + 8, SU = 24 and
TU = 2x – 4, what does ST = ?

Step-by-step explanation:
For TU is it -2x-4 or 2x-4 cause the question and what on your paper are different
Answer:
20
Step-by-step explanation:
ST= SU - TU
=24 - (2x-4)
=24-2x+4=28-2x
but. 2x-4+3x+8 = 5x+4 = 24
5x=24-4=20
x=20/5=4
so ST=28-2x= 28-2(4)
ST=20
