4b+5=1+5b --> 5=1+1b --> 4=b
Answer:
21
Step-by-step explanation:
Put them equal to eachother
(10x-29)=(8x+3)
2x=42
x=21
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.
