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

Solve the following linear equation: 3(5z-7)-2(9z-11)=4(8z-13) .

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

Add the following rational numbers : (i) (12)/(7) and (3)/(7) : (ii) (-2)/(5) and (1)/(5) (iii) (3)/(8) and (1)/(8) (iv) (-5)/(11) and (7)/(-11) (v) (9)/(-13) and (-11)/(-13) (vi) (-2)/(9) and (5)/(9) (vii) -(17)/(9) and (-11)/(9) (viii) (-3)/(7) and (5)/(-7)

Evaluate : (i) (3)/(4)-(4)/(5) (ii) -3-(4)/(7) (iii) (7)/(24)-(19)/(36) (iv) (14)/(15)-(13)/(20) (v) (4)/(9)-(2)/(-3) (vi) (7)/(11)- (-4)/(-11) (vii) (-5)/(14) -(-2)/(7) (viii) (-5)/(-8)-(-3)/(4)

Verify the following: (i) ((3)/(4)+(-2)/(5))+(-7)/(10)=(3)/(4)+((-2)/(5)+(-7)/(10)) (ii) ((-7)/(11)+(2)/(-5))+(-13)/(22)=(-7)/(11)+((2)/(-5)+(-13)/(22)) (iii) -1+((-2)/(3)+(-3)/(4))=(-1+(-2)/(3))+(-3)/(4)
