Answer:

1. 2t+7

2. -8y + 4

3. 3/2s-6.8

4. -5w-5/2

5. 11k+6

6. 13.6g-28

7. 3p+1

8. 4k-13/5

9. -6u+7

10. 11.4h-26

11. 2j-8

12. -28x - 55

13. 4.5b + 24

14. 6n + 22/5

Step-by-step explanation:

1. (5 - t) + (3t + 2)

Let's add the variables first. -t + 3t = 2t. Now do 5+2 for 7, and you will get 2t+7

2. 2(-5y +6) + (2y -8)

First, distribute the left side. (-10y + 12) + (2y - 8)

Then, add the variables -10 + 2 = -8y

Now, add the constants 12+ - 8 = 4

-8y + 4

3. 5(0.3s - 2) + 2(5 - 3.4)

Distribute first, on both sides, and you will get (3/2s-10)+(10-6.8)

There are no other variables, so we just add the constants.

-10+10-6.8 = -6.8. So we get

3/2s-6.8

4. 1/5(-15w - 20) + 1/2(3 - 4w)

Distribute both sides, this will give (-3w-4)+(3/2-2w)c.

Now add the variables. -3w+-2w = -5w

Then do -4+3/2 for -5/2.

-5w-5/2

5. (7k + 9) + (4k - 3)

Add the variables, 7k+4k=11k, then Add the constants. 9+-3= 6.

11k+6

6. 4(2.5g - 4) + 3(1.2g - 4)

Distribute and you will get (10g-16)+(18/5g-12).

Add the variables for 68/5g (or 13.6g)

Add the constants, -16+-12 = -28.

13.6g-28

7. 1/3(6p - 3) + 1/7(7p + 14)

Distribute first. (2p-1)+(p+2)

Add variables, 2p+p = 3p

Add constants, -1 + 2 = 1

3p+1

8. 1/8(16k - 24) + 1/5(2 + 10k)

Distribute first.

(2k - 3) + (2/5 +2k)

Add variables, 2k+2k = 4k

Add constants, -3+2/5 = -13/5

4k-13/5

9. (8 - u) - (5u +1)

Subtract the variables.

-u-5u =-6u

Subtract constants, 8-1 = 7.

-6u+7

10. (3h + 4) - 6(5 - 1.4h)

Distribute first, (3h+4)-(30-8.4h)

Subtract variables. 3h- -8.5h = 11.4h

Subtract constants. 4-30 = -26

11.4h-26

11. 1/4(16j - 12) - 1/9(18j + 45)

Distribute, (4j-3)-(-2j+-5)

Subtract variables, 4j-2j = 2j

Subtract constants, -3 - 5 = -8

2j-8

12. (2x + 7) - 6(5x - 8)

Distribute first. (2x+7)-(30x-48)

Subtract variables, 2-30 = -28x

Subtract constants, 7- - 48 = 55

-28x - 55

13.  (12 + 7.2b) - 3(0.9b - 4)

Distribute,

(12+7.2b) - (2.7b-12)

Subtract variables. 7.2b-2.7b = 4.5b

Subtracts constants. 12- - 12 = 24

4.5b + 24

14. 2/3(12n + 6) -1/5(10n - 2)

Distribute,

(8n + 4) - (2n - 2/5)

Subtract variables, 8n-2n = 6n

Subtracts constants, 4 - - 2/5 = 22/5

6n + 22/5

Sorry this took so long, showing your work for simplification is tedious.
