(1 pt. each) 1. 5x – 3 = 17 2. 2 – 8x = -22 3. 4(3x – 1) = 10 4. -10 = a 5. 8(y – 1) – y = 2y + 7 6. x - 9 = 15 7. 3(2a + 1) = -5(a + 6) 8. 4 – (2y + 5) = 3(1 – 4y) 9. - 11 = 10. 4x – 3 + 7x – 1 = 2x + 3 – 9x - 5 hurry and me

1 ) 5x - 3 =17 
          +3   +3

      5x = 20
    x = 4 

2) 2 - 8x = - 22
    -2           -2
     -8x = - 24 
       x = 3

3) 4 ( 3x - 1) = 10
    12x - 4 = 10
           +4    +4 
    12x = 14
     x = 7/6

5) 8 ( y - 1 ) - y = 2y + 7
      8y - 8 - y = 2y + 7
          7y - 8 = 2y +7
          -2y        -2y
      5y - 8 = 7
           +8    +8
       5y = 15
         y = 3

6) x - 9 = 15 
       +9    +9

      x = 24 

7) 3(2a + 1) = -5(a + 6)
    
        6a + 3 = -5a - 30
        +5a        +5a
       
        11a + 3 = -30
               -3      -3
         11 a = -33
        a = - 3 

8) 4 – (2y + 5) = 3(1 – 4y)

       4 - 2y - 5 = 3 - 12y 
           -2y - 1 = 3 - 12y
           +12y          +12y
 
           10y - 1 = 3
                  +1   +1

            10y = 4
 
            y = 2/5

10) 4x – 3 + 7x – 1 = 2x + 3 – 9x - 5

         11x - 4 = - 7x - 2
         +7x          +7x

       18x - 4 = -2 
              +4    +4

        18x = 2 

         x = 1 / 9
