3b + 6 = 12 3b = 6 b = 2

If a + b = 6, what is the value of 3a + 3b?

b = -8

b = -6

12a + 6b + 6c = 6(2a + b + c)

6+7a+6b

3b + 2a = 2 and -2 + a = 8 -2 + a = 8 can be rearranged to show a = 8 + 2 = 10 (Effectively 2 has been added to both sides.) As a = 10, the value for a can now be substituted in the equation 3b + 2a = 2 3b + 2x10 = 2 : 3b + 20 = 2 this can be rearranged to show 3b = 2 - 20 = -18 and dividing both sides by 3 gives b = -6.

1 plus 19 equals 20 2 plus 18 equals 20 3 plus 17 equals 20 4 plus 16 equals 20 5 plus 15 equals 20 6 plus 14 equals 20 7 plus 13 equals 20 8 plus 12 equals 20 9 plus 11 equals 20 10 plus 10 equals 20 1 times 20 equals 20 2 times 10 equals 20 4 times 5 equals 20

-6(a-3b-9c)

It is: 4b+6

20 + 6 - 56 = -30

The equation (b2 - 2b) + (3b - 6) = b2 + b - 6

How about 20 plus 6 equals 26 as one example

y=2

9 - - 6 + 20 = 35

6-4-8-2=20 is the answer

5+3b? :3

x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.

The number is 21.

P = p + at 82 = 76 + a*20 6 = a*20 6/20 = a that is a = 3/10 or 0.3 That is the answer.

(a + 3)( b + 2)
