a = 3
If a + b = 6, what is the value of 3a + 3b?
a + a + a - 2a = 3a - 2a = a
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c

a = 3
If a + b = 6, what is the value of 3a + 3b?
a + 3a + 5a = 180 9a =180 a = 20
2a + 3a + 4 = 5a + 4
a + a + a - 2a = 3a - 2a = a
1
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
a is equal to 4
3a + 9 =3X(a + 3)
12
12a
3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.
