Pamela is incorrect. When you multiply anything negative by a negative, the product will always be a positive. Because the two negative signs cancel each other out.
1. 4x - y = 8
4x = y + 8
Y = 4x - 8
2. 2x + 3y = 4
3y = -2x + 4
Y = -2/3x + 4/3

We need to cross multiply to find this one.
9/146 = x/100
X100 X100
9 /146 = x
x = 6.164383562
