Answer: 7

Step-by-step explanation:

  1. 2x(3x-5) -3(x-3)
  2. 2(2)(3(2)-5) -3(2-3)      First you substitute 2 for all the x's. The twos in  .                                      parentheses  represent multiplication.
  3. 4(6-5) -3(2-3)               Second, you multiply 2 by 2, which equals 4,           .                                     and multiply 3 by 2, which equals 6.
  4. 4(1) -3(-1)                       Next, you solve the problems in the                          .                                      parentheses, which is 6 minus 5 is 1, and 2          .                                      minus 3 is -1
  5. 4-(-3)                              Next, you multiply 4 by 1, which is 4, and                .                                      multiply 3 by -1.
  6. 4+3                                Since two negatives make a positive, the             .                                     equation changes to 4 plus 3.
  7. 7                                     Finally, you add 4 plus 3 and get 7.

P.S: Sorry about the random periods. I had to put them in to format it like that.
