HELP ASAP!! ILL MARK BRAINLIST IF RIGHT

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.

What is the 9th term in the geometric sequence described by this explicit formula? an=-6. (2)(n-1) apex

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.
