Answer:
(8a + 2b − 4) and (3b − 5)
Remove bracket,
8a + 2b - 4 + 3b - 5
Group like terms,
8a + 2b + 3b - 9
Add similar elements,
8a + 5b - 9
X=mumber of boys
y=number of girls.
I suggest this system of equations:
x+y=30
x=4y
We can solve this system of equations by susbtitution method.
4y+y=30
5y=30
y=30/5=6
x=4y
x=4*6=24
Answer: there are 6 girls
