3 squared=9 3 squared=3*3 3*3=9
3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
5b - 3 - 2b = 6b - 3 3b - 3 = 6b - 3 3b - 6b = 3 - 3 b = 0

2b + 3 b = 12 . 27 since the beginning is 2 x 12, which equals 24, and then you have to add the extra 3.

7(3y-2)-(-4y+9)
The greatness of 4 squared and 3 squared is expressed by the equation: 16 - 9 which equals 7.3 squared equals 3 x 3 = 94 squared equals 4 x 4 = 1616 - 9 = 7
3 squared=9 3 squared=3*3 3*3=9
3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
3 squared = 9 9 - 2 x 1 = 9 - 2 = 7
5b - 3 - 2b = 6b - 3 3b - 3 = 6b - 3 3b - 6b = 3 - 3 b = 0
2B + 3 = 18 B = 7.5 18 - 3 = 15 2 /15 = 7.5 If the answer is "18", you need to take the "3" away that you have added. After taking the "3" away, it will be easier to figure out what "B" equals. Now, because you have taken away the "3", you are left with "2B". "2B", meaning "2 x B", just means you need to do the opposite to figure out the answer, therefore being "2 / B". Because you took the "3" and you had "15" left over, you will just have to half that, therefore "B" equals "7.5".

8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
4/b-3 + 3/b = -2b/b-3 b = 1 or b = -4.5
