(C) 5 (D) 6



with explain​

Answer 1

Answer:

Hey ..!!!

Here is ur answer...!!!

Given is....

(5+9x)/(15x-3) = 2/3

(5+9x) = (15x-3) × 2/3

5+9x = (30x-6)/3

3×(5+9x) = 30x-6

15+27x =30x -6

15+6 = 30x-27x

21 = 3x

x = 21/3

x = 7

So , option (a) is correct...!!

Hope this helps....❤️☺️❣️

Answer 2

Answer:

Step-by-step explanation:

→ (5 + 9x) : (15x - 3) = 2 : 3

→ 5+9x/15x-3 = 2/3

→ Now cross multiplication

→ 3(5+9x) = 2(15x-3)

→ 3 × 5 + 3 × 9x = 2 × 15x - 2 × 3

→ 15 + 27x = 30x - 6

→ 15 + 6 = 30x   -  27x

→ 21 = 3x

→ 3x = 21

→ x = 21/3

→ x = 7

so,

→ (A)7
