3a = 1a = 1/3 (a third)
If a + b = 6, what is the value of 3a + 3b?
3a - 7 = -28 Therefore, 3a = -21 a = -21/3 Therefore, a = -7
12
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
3a=1divide both sides by 3a=1/3
-3a-12 = 12+12 +12-3a = +12~ ~-3 -3a = -8
3a = 1a = 1/3 (a third)
3a = 21 Therefore, a = 21/3 a = 7
a = -5
If a + b = 6, what is the value of 3a + 3b?
3a - 7 = -28 Therefore, 3a = -21 a = -21/3 Therefore, a = -7
P = 3a - 3q Add 3q to each side: P + 3q = 3a Double each side: 6a = 2P + 6q
3a + 9 =3X(a + 3)
12
3a x 2a =24
If: -3a-1 = -15 Then: a = 4 and 2/3
