    1. 9t

    2. -3g

    3. 4b + 4

  • Here you have to do any addition/subtraction possible

    1) 3t + 6t

    9t

    2) 2g - 5g

    -3g

    3) -b - 3b + 8b + 4

    -4b + 8b +4

    4b + 4

    Explanation:

    Here "b" or "g" or "t" can be any number.

    for example, in

    1) 3t + 6t

    Let's imagine t = 2

    Scenario A)

    3t + 6t

    = (3 x 2) + (6 x2)

    = 6 + 12

    = 18

    Scenario B)

    3t + 6t

    = 9t

    = 9 x 2

    = 18

    Either way, the answer is the same, so we can directly add 3t and 6t without worrying about getting an incorrect answer.

    enjoy!

    1. 3t+6t=t(3+6)=9t

    2. g(2-5)=-3g

    3. -b-3b+8b+4=b(-1-3+8)+4=4b+4

    OK, here is some math HELP (but not the answers)

    Add the constants, keep the variables.

    For example, 14s + 4s = (14 + 4)s = 18s

    32y - 10y = (32 - 10)y = 22y

    Now you try.

    3t+6t = 9t

    2g-5g=-3g

    -b-3b+8b+4 = -4b+8b+4= 4b + 4

    First, you find the GCF of 3t and 6t. The GCF is 3t, so you divide 3t by 3t, and 6t by 3t. You will get 1 and 2, so the answer is 3t(1+2)
