(2) + (2)
=> 8x - 6y = -46 ———(3)
(1) + (3)
=> 5x + 6y + (8x - 6y) = 20 - 46
=> 13x + (6-6)y = -26
=> 13x + 0y = -26
=> 13x = -26
=> x = -26/13
=> x = -2
=> 5(-2) + 6y = 20
=> 6y = 20 + 10
=> 6y = 30
=> y = 5
x = -2, y = 5 => C
1. multiply 5 inside of the parenthesis
5x+10
2. multiply the 2 inside the parenthesis and add the variables
9x-2
9x(y+4)-10(y+4)
(9x-10)(y+4)
