If `(2y)/(7)=(y+3)/(4),` then `y=`

If the LCM of the polynomials (y -3)^(a) (2y + 1)^(b) (y + 13)^(7) and (y -3)^(4) (2y +1)^(9) (y + 13)^(c) " is " (y - 3)^(6) (2y +1)^(10) (y + 13)^(7) , then the least value of a + b +c is

If 4/7+2/7=y/21 then y=

(7Y + 4)/(Y+2)=(-4 )/(3)

Equation (3y+1)/(2)=(7y-5)/(4) is simplified to

((1) / (3) y ^ (2) - (4) / (7) y + 5) - ((2) / (7) y- (2) / (3) y ^ (2) +2 ) - ((1) / (7) y-3 + 2y ^ (2))

If |(3x+4y,-3),(2,x+2y)|=|(7,-3),(2,3)| then x and y are

Solve for x and y : (y+7)/(5)=(2y-x)/(4)+3x-5 (7-5x)/(2)+(3-4y)/(6)=5y-18

If (7x-5y):(3x+4y) = 7:11 then show that (3x-2y): (3x+4y) = 137 : 473
