X is the amount of groups
y is the amount of people
42- 3x = 30
x (8) = y
42 - 3x = 30
-42 -42
-3x = -12
divide by -3
x = 4, there were 4 groups of 8, substitute the 4 into the other equation
4×8 = 32
y = 32 , There are 32 people in Marcos group
sorry, it's the best I could do.

Step-by-step explanation
Hope it helps!
Answer:
R__S__T
RT = RS + ST
6x – 4 = ( 4x – 3) + ST
(6x – 4 ) – ( 4x – 3 ) = ST
(6x – 4 ) +( – 4x + 3 ) = ST
2x – 1 = ST
ST = 2x – 1
RS=ST
4x – 3 = 2x – 1
4x – 2x = – 1 +3
2x = 2
x= 2/2
x =1
ST = 2x – 1 = 2(1) – 1 =2 ‐ 1 = 1
ST = 1
I hope I helped you^_^
