How do you solve these types of problems?

1) 3 - n = 32
3m - 8n - 6 = 0

2) 2p - q = 8
1/3p + 1/4q = 3

  • Algebra 1- 8th Grade -

    1. substitute -29 for n in the second equation, and solve for q.
    (n=-29 comes from the first equation)

    2. Multiply the second equation by 4 and add them.
    2p - q = 8
    4/3p + q = 12
    10/3 p = 20
    p = 6
    q = 2p - 8 = 4
