3(5x-7)-2(9x-11)=4(8x-13)-17

3(5a-7)-2(9a-11)=4(8-13-1)

If 3 (5x-7) -4 (8x-13) =2 (9x-11)-17 , then the value of (7x-5)/(11x-9) is

If 3 ( 5x - 7) - 4 ( 8x - 13) = 2 ( 9x - 11) - 17, then the value of ( 7x - 5)/(11 x - 9) is

Solve the following: 3 (5x – 7) + 2(9x – 11) = 4(8x – 7) – 111

Check whether the following are quadratic equations : (1) (x-3)^(2)=x(2x-5) (2) (2x-3)(8x+1) = (4x+5)(4x-5) (3) (5x+3)(x-2)=(4x+3)(2x-1) (4) (2x+5)^(3)=8(x-1)^(3) (5) x^(2)+7x-8=x(x+5) (6) x^(3)+9x^(2)-7x+2=(x+3)^(3)
