Question

"Solve 3x + 5/2x + 1 = 1/3"

Answer 1

Answer:

"-2

Step-by-step explanation:

(by cross multiplication)

= 3(3x + 5) = (2x +1)

= 9x + 15 = 2x + 1

= 9x - 2x = 1 - 15

= 7x = -14

x = -14/7 = -2"

Answer 2

Step-by-step explanation:

"Solve 3x + 5/2x + 1 = 1/3".

• $3x + 5 + 1 = \frac{1}{3} \times 2x+1$
• $3x + 5 = \frac{2x+1}{3}$
• $3(3x + 5) = 2x+1$
• $9x + 15-1 = 2x$

• $9x + 14 = 2x$
• $9x - 2x = - 14$
• $7x = - 14$
• $x = \frac{ - 14}{7}$
• $x = - 2$
