  1. Find the point of intersection for each set of equations below using any method. Check your solutions, if possible. Homework Help ✎

    1. 6x − 2y = 10
      3x − 5 = y

    2. 6x − 2y = 5
      3x + 2y = −2

    3. 5 − y = 3x
      y = 2x

    4. y = 1/4x+ 5
      y = 2x − 9

Substitution is one way to solve this system.

Distribute the left side.

Combine like terms.

6x − 2(3x − 5) = 10

6x − 6x + 10 = 10

10 = 10
