We know that (a = -3), (b = 2), (c = 5), and (d = -4).
----------------------------------------------------------------------
Solution #1:
≈ 1.57
----------------------------------------------------------------------
Solution #2:
= a - 4b / 3c + 2d
= (-3) - 4(2) / 3(5) + 2(-4)
= (-3) - 8 / 15 + (-8)
= (-3) - 0.53 + (-8)
= (-3.53) + (-8)
= -11.53
----------------------------------------------------------------------
Solution #1 Answer: 1.57
Solution #2 Answer: -11.53
