9/8 because in dividing you multiply by the reciprocal so 3/4 x 3/2= 9/8
The coordinates for point a are (-3,5)
The first point tells you the x value and the second tells the y value
X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
C > 3:
c -10 + 3c > 2
combine like terms
4c -10 > 2
+10 +10
4c > 12
divide both by 4
c > 3
