Given that 3x-y : x+2y = 2 : 5, Determine the ratio x:y

N76 [4]

Answer:

x : y = 9 : 13

Step-by-step explanation:

Given that

3x - y : x + 2y = 2 : 5

Express the ratio in fractional form, that is

$\frac{3x-y}{x+2y}$ = $\frac{2}{5}$ ( cross- multiply )

5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )

15x - 5y = 2x + 4y ( subtract 2x from both sides )

13x - 5y = 4y ( add 5y to both sides )

13x = 9y ( divide both sides by 13 )

x = $\frac{9}{13}$ y ( divide both sides by y )

$\frac{x}{y}$ = $\frac{9}{13}$ , that is

x : y = 9 : 13

HACTEHA [7]

$\\ \sf\longmapsto \dfrac{3}{x-4}=\dfrac{6}{x-5}$

$\\ \sf\longmapsto 3(x-5)=6(x-4)$

$\\ \sf\longmapsto 3x-15=6x-24$

$\\ \sf\longmapsto 3x-6x=-24+15$

$\\ \sf\longmapsto -3x=-9$

$\\ \sf\longmapsto x=\dfrac{-9}{-3}$

$\\ \sf\longmapsto x=3$

$\\ \sf\longmapsto KM=3+6=9$
