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

Answer:

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
