c / 4 = 3
c = 12
2a – 4 = -14
a = -5
-3m = -27
m = 9
4x + 2 = x - 7
x = -3
15 – 2x = 17 – 3x
x = 2
a = 3, 2a + 1 = ?

x = 4, x2 – 3x = ?

m = 2, p = 4
2m – 3p = ?

r = -3 and t = -1
3r / (t + 5) = ?

4b + 6 = 14
b = 2
(x + 4)(x – 3) = 0
x = -4 and x = 3
(2a + 6)(a – 2) = 0
a = -3 and a = 2
(4a + 2) / 9 = 2
a = 4
c2 + 5c + 6 = 0
ie (c + 3)(c + 2) = 0,
so c = -3 and -2
