Solve for the value of each letter.

1. 6x + 10 = 28

2. - 2m - 4 = 8

3. x + x + 2x = 48

4. 3y + 4 + 3y - 6 = 34

5. 9 (w - 6) = 36

6. - 5 (t + 3) = - 30

7. 5z + 2 = 3z - 10

8. 11 + 3x + x = 2x - 11

9. - 5 (n - 1) = 7 (n + 3)

10.-3 (c - 4) - 2c - 8 = 9 (c + 2) + 1

Step-by-step explanation:

1] 6x + 10 = 28 {subtract 10 from both sides}

6x + 10 - 10 = 28 - 10

6x = 18 {Divide both sides by 6}

6x/6 = 18/6

x = 3

2] - 2m - 4 = 8 {Add 4 to both side}

-2m - 4 + 4 = 8 + 4

-2m = 12 {Divide both sides by - 2}

-2m/-2 = 12/-2

m = - 6

3] x + x + 2x = 48 {add the like terms}

4x = 48 {divide both sides by 4}

4x/4 = 48/4

x = 12

4] 3y + 4 + 3y - 6 = 34 {add the like terms}

6y - 2 = 34 {Add 2 to both side}

6y - 2 + 2 = 34 + 2

6y = 36 {divide both sides by 6}

6y/6 = 36/6

y = 6

5]9 (w - 6) = 36 {divide both sides by 9}

[9 (w - 6) ]/9 = 36/9

w - 6 = 4 {Add 6 to both sides}

w - 6 + 6 = 4 + 6

w = 10
