In Exercises 23–25, solve each equation. If the solution set is Ø
or (-0, ), classify the equation as an inconsistent equation or
an identity.
23. 3(2x – 4) = 9 – 3(x + 1)
2x
24.
x - 4
x + 1
4
2
4
25. 3(x – 4) + x = 2(6 + 2x)
Exercises 43–52: Complete the following.
(a) Solve the equation symbolically.
(b) Classify the equation as a contradiction, an identity,
or a conditional equation.
43. 5x - 1 = 5x + 4
44. 7- 9: = 2(3 – 42) – z
45. 3(x - 1) = 5
46. 22 = -2(2x + 1.4)
47. 0.5(x – 2) + 5 = 0.5x + 4
48. 눈x-2(x-1)3-x + 2
2x + 1
2x

52. 0.5 (3x - 1) + 0.5x = 2x – 0.5
For Exercises 5–10,
a. Simplify the expression.
b. Substitute 0 for h in the simplified expression.
2(x + h)? + 3(x + h) ·
5.
