Question

7.(x-3)-5.(3-x)=11x-5

giúp mk

Answer 1

7x - 21 -15 + 5x = 11x - 5

12x - 36 = 11x - 5

12x - 11x = - 5 + 36

x = 31

Answer 2

TA có 7(x-3)-5(3-x)=11x-5

<=> 7x-21-15+5x=11x-5

<=> 12x-36=11x-5

<=>12x-11x=36-5

<=>x=31

Vậy x=31

Answer 3

7 ( x - 5 ) - 5 ( 3 - x ) = 11x - 5

7x - 35 - 15 + 5x = 11x - 5

7x + 5x - 11x  = 35 + 15 - 5

x = 45
