y(9x)/(3)+1=(7x)/(13)+3

Consider the lines (x-5)/(3)=(y-7)/(-16)=(z-3)/(7) and (x-9)/(3)=(y-13)/(8)=(z-15)/(-5) , then-

Simplify: ((13)/(9)x(-15)/(2))+((7)/(3)x(8)/(5))+((3)/(5)x(1)/(2))

Solve : (7x +3)/(4) + (9x -5)/(8) = (16x-3)/(16) The following steps are involved in solving the above problem. Arrange them in sequential order (A) x = (-5)/(30) = (-1)/(6) (B) (7x + 3)/(4) + (9x -5)/(8) = (16x-3)/(16) rArr (14x + 6 + 9x -5)/(8) = (16x -3)/(16) (C) (23x + 1)/(8) = (16x -3)/(16) rArr 23x + 1 = (16x -3)/(2) (D) 46x + 2 = 16x - 3 rArr 30 x = -5

If 2x+3y=34 and (x+y)/(y)=(13)/(8), then find the value of 5y+7x

Solve for x and y:(2x+1)/(7)+(5y-3)/(3)=12(3x+2)/(2)-(4y+3)/(9)=13

Solve by cross-multiplication method. (i) 8x-3y=12,5x=2y +7 (ii) 6x+ 7y -11 =0, 5x+ 2y =13 (iii) (2)/(x)+(3)/(y) =5, (3)/(x) -(1)/(y) +9=0

if (8x + l3y)/(8x - 13y) = (9)/(7) , find x : y .

(4)/(x)+(3)/(y)=1,(8)/(x)-(9)/(y)=7

Simplify : (i) (5x - 9y) - (-7x + y) (ii) (x^(2) -x) -(1)/(2)(x - 3 + 3x^(2)) (iii) [7 - 2x + 5y - (x -y)]-(5x + 3y -7) (iv) ((1)/(3)y^(2) - (4)/(7)y + 5) - ((2)/(7)y - (2)/(3)y^(2) + 2) - ((1)/(7)y - 3 + 2y^(2))
