Solve each of the following systems of equations.
(a) 3x + 2y = −1
5x + 3y = −2
(b) 4x −5y = 25
3x + 2y =13
(c) y = -10x
3y = 29 – x
(d) 2y = 3x + 17
3x = 11 – 5y
(e) 2x −3y =13
3x − 2y =12
(f) 2x = 3y -11
y =13+ 3x
(g) 2a = -3b -14 = 0
a + b – 2 = 0
(h) a + c = - 10
8a + 4c = 0
(i) 3b – 3c = -15
-2b + 4c = 14
(j) 48a – 32b = 128
16a + 48b = 32
(k) 0.5m + 0.3n = 54
0.3m + 0.7n = 74
(l) ¾ m + 5/8 n = 3/4
5/6 n + 2/3 m = 7/9
