Question

15.(2x-3) = 6.(7x-3).

Answer 1

Ta có: 15(2x - 3) = 6(7x - 3)

=> 30x - 45 = 42x - 18

=> 42x - 30x = -45 + 18

=> 12x = -27

=> x = -27/12

                                               Vậy x = -27/12

Answer 2

15.(2x-3) = 6.(7x-3).

=> 30x-45=42x-18

=> -12x=27

=> x = -27 /12 

Answer 3

sai

15.(2*-3)=-90

6.(7*-3)=-126

Answer 4

\(15\left(2x-3\right)=6\left(7x-3\right)\)

\(=>30x-45=42x-18\)

\(=>30x-42x=45-18\)

\(=>-12x=27\)

\(=>x=\frac{-9}{4}\)

Answer 5

\(15\left(2x-3\right)=6\left(7x-3\right)\)

\(30x-45=42x-18\)

\(30x-42x=-18+45\)

\(-12x=27\)

\(x=-\frac{9}{4}\)

Answer 6

15(2x-3)=6(7x-3)

30x-45=42x-18

-12x=27

x=-9​​​​/4

Answer 7

15.(2x-3) = 6.(7x-3)

=>30x-45=42x-18

=>30x-42x=45-18

=>-12x=27

=>x=-9/4.Vậy x=-9/4
