Answer 2

x = 9

y = 10

Explanation:

Given:

(4×+3y ) : (3×+5y) = 6:7

To find:

x:y​

==> We can write the ratio in the fraction format

(4×+3y )/(3×+5y) = 6/7

By doing cross multiplication,

(4x+3y) 7 = 6(3×+5y)

28x+21y = 18x+30y

28x-18x =30y-21y

10x = 9y

x /y = 9/10

Numerator in LHS is x = Numerator in RHS is 9

Denominator in LHS is y = Denominator in RHS is 10

x = 9

y = 10
