Answer:

A) 1.5

B) x^2-23x+42 = (x-2)(x-21)

C) x=2, x=21

Step-by-step explanation:

a) 15 -2x / 3 = 4

15-2x = 12  (Times by three on both sides)

-2x = -3

x = -3/-2 = 3/2 = 1.5

b) x^2-23x+42

x^2-23x+42 = (x-2)(x-21)

c) x^2 -23x +42 = 0

x=2, x=21

(x-2) = 0  ⇒  x = 2

(x-21) = 0  ⇒  x = 21

Answer:

x = -3\frac{11}{20}

Step-by-step explanation:

Convert the mixed fractions to improper fractions;

⇒\frac{-19}{4} = x - \frac{6}{5}  

⇒ \frac{-71}{20} = x   [add 6/5 to both sides]

⇒ x = -3\frac{11}{20}   [convert to mixed fraction]
