Put the steps in the correct order to solve this multistep equation.

  1. undo subtract 6 by adding 6 to both sides of the equations to get 13k = 13

  2. undo multiplying by 13 by dividing by both sides of the equation by 13 to get k = 1

  3. Use distribution to multiply (5k-3) by 2 to get 3k+10k-6=7

  4. Simplify like terms to get the equation 13k - 6 = 7

  5. The solution is k = 1

  6. Check the solution by evaluating the original expression 3k+2(5k-3) to verify that it equals 7
