Answer:
A
3(2x -5)-2(x-5)=3.(2x)-3.(5)-2.x-2.(-5)
=6x-15-2x+10
=4x-5
96 prime factors (2•2•2•2•2•3)
144 prime factors (2•2•2•2•3•3)
Actual factor of 96 (1,2,34,6,8,12,16,24,32,48,96)
Actual factors of 144 (1,2,3,4,6,8,9,12,16,18,24,36,48,72,144)

Answer:
(x, y) = (1, -1)
Step-by-step explanation:
The augmented matrix of coefficients for these equations is ...
![\left[\begin{array}{cc|c}2&-5&7\\-2&4&-6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D2%26-5%267%5C%5C-2%264%26-6%5Cend%7Barray%7D%5Cright%5D)
The row-reduction function of your calculator can find the solution to the system of equations. The result of using that function is ...
![\left[\begin{array}{cc|c}1&0&1\\0&1&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%260%261%5C%5C0%261%26-1%5Cend%7Barray%7D%5Cright%5D)
This tells you the solution is (x, y) = (1, -1).
Use long or synthetic division
The correct choice is B
