Question

can anyone please help me finding the solution​

Answer 1

Answer:

do cross multiplication and then solve them

Answer 2

Answer:-

11. $\frac{6}{3m + 1}$ = $\frac{9}{5m - 3}$

⇒6(5m - 3) = 9(3m + 1)            [by doing cross multiplication]

⇒30m - 18 = 27m + 9

⇒30m - 27m = 9 + 18

⇒3m = 27

⇒m = $\frac{27}{3}$

⇒m = 9

12. $\frac{2x + 3}{5}$ = $\frac{4x + 9}{11}$

⇒11(2x + 3) = 5(4x + 9)

⇒22x + 33 = 20x + 45

⇒22x - 20x = 45 - 33

⇒2x = 12

⇒x = $\frac{12}{2}$

⇒x = 6

Hope it helps u.
