Question

1. 3q + 8 = q
2. -3/4 y = -3/8
3. 1/4 a = 2/3

Answer 1

1. 3q - q = 8
    2q = 8
    q = 8/2
    q = 4
2. [-3/4y = -3/8] x 8
    -6y = -3
    y = -6/-3
    y = 2
3. [1/4a = 2/3] x 12
    3a = 8
    a = 8/3   

Answer 2

1. 3q + 8 = q
    2q + 8 = 0
           2q = -8
             q = -4

2. - 3/4 y = - 3/8
           y = - 3/8 x - 4/3
           y = 12 / 24
              = 1/2

3. 1/4 a = 2/3
         a = 2/3 x 4/1
         a = 8/3
            = 2 2/3
