In what step is there first an error. explain the error and how to correctly work the problem.
given: 2(10-13x)+9x=-34x+60
step 1: 17x=-34x+40
step 2: 17x=-34x+40
step 3: 51x = 40
step 4: x=40/51
(this is a lot of points be thorough)

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
